Quantum Aspects of Life by Derek Abbott,Paul C W Davies,Arun K Pati Pdf
This book presents the hotly debated question of whether quantum mechanics plays a non-trivial role in biology. In a timely way, it sets out a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. The acronym BINS, for Bio-Info-Nano-Systems, has been coined to describe the synergetic interface of these several disciplines. The living cell is an information replicating and processing system that is replete with naturally-evolved nanomachines, which at some level require a quantum mechanical description. As quantum engineering and nanotechnology meet, increasing use will be made of biological structures, or hybrids of biological and fabricated systems, for producing novel devices for information storage and processing and other tasks. An understanding of these systems at a quantum mechanical level will be indispensable. Contents:Foreword (Sir R Penrose)Emergence and Complexity:A Quantum Origin of Life?

Life on the Edge by Johnjoe McFadden,Jim Al-Khalili Pdf
New York Times bestseller • Life on the Edge alters our understanding of our world's fundamental dynamics through the use of quantum mechanics. Life is the most extraordinary phenomenon in the known universe; but how did it come to be? Even in an age of cloning and artificial biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we still missing a vital ingredient in its creation? Using first-hand experience at the cutting edge of science, Jim Al-Khalili and Johnjoe Macfadden reveal that missing ingredient to be quantum mechanics. Drawing on recent ground-breaking experiments around the world, each chapter in Life on the Edge illustrates one of life's puzzles: How do migrating birds know where to go? How do we really smell the scent of a rose? How do our genes copy themselves with such precision? Life on the Edge accessibly reveals how quantum mechanics can answer these probing questions of the universe. Guiding the reader through the rapidly unfolding discoveries of the last few years, Al-Khalili and McFadden describe the explosive new field of quantum biology and its potentially revolutionary applications, while offering insights into the biggest puzzle of all: what is life? As they brilliantly demonstrate in these groundbreaking pages, life exists on the quantum edge. Winner, Stephen Hawking Medal for Science Communication

Quantum Tunnelling in Enzyme-catalysed Reactions by Rudolf K. Allemann,Nigel S. Scrutton Pdf
In recent years, there has been an explosion in knowledge and research associated with the field of enzyme catalysis and H-tunneling. Rich in its breath and depth, this introduction to modern theories and methods of study is suitable for experienced researchers those new to the subject. Edited by two leading experts, and bringing together the foremost practitioners in the field, this up-to-date account of a rapidly developing field sits at the interface between biology, chemistry and physics. It covers computational, kinetic and structural analysis of tunnelling and the synergy in combining these methods (with a major focus on H-tunneling reactions in enzyme systems). The book starts with a brief overview of proton and electron transfer history by Nobel Laureate, Rudolph A. Marcus. The reader is then guided through chapters covering almost every aspect of reactions in enzyme catalysis ranging from descriptions of the relevant quantum theory and quantum/classical theoretical methodology to the description of experimental results. The theoretical interpretation of these large systems includes both quantum mechanical and statistical mechanical computations, as well as simple more approximate models. Most of the chapters focus on enzymatic catalysis of hydride, proton and H" transfer, an example of the latter being proton coupled electron transfer. There is also a chapter on electron transfer in proteins. This is timely since the theoretical framework developed fifty years ago for treating electron transfers has now been adapted to H-transfers and electron transfers in proteins. Accessible in style, this book is suitable for a wide audience but will be particularly useful to advanced level undergraduates, postgraduates and early postdoctoral workers.
This book intends to give a systematic exposition of the validity of quantum principles in biological systems. There are two types of applications of quantum theory in physical systems -- the 'trivial applications' and 'non-trivial applications'. Since every object in this universe consists of atoms and molecules, they should be described by the laws of quantum theory -- which we call trivial applications. On the other hand, there exist some systems where the observational results cannot be explained by the laws of classical physics and this requires a change of paradigm -- these are known as non-trivial applications. Many authors pointed out such non-trivial applications of quantum theory to explain how some biological systems function. In this book, we review such kinds of results in a systematic manner which clearly indicates the need to change the paradigm to understand these biological systems better.

NEUROQUANTOLOGY: QUANTUM PHYSICS IN BRAIN by SULTAN TARLACI Pdf
Although quantum mechanics has been around since the beginning of the 20th century, it is only in the last twenty or thirty years that it has begun to find practical applications in everyday life. And in the past twenty years in particular, those working on quantum mechanics and neuroscience have begun to take an interest in each other’s fields. First physicists took an interest in the nervous system, and later, not to be outdone, neuroscientists started to look at quantum physics. In addition, despite there not being a suitable platform, conferences on quantum physics strangely became the scene for discussions on the concepts of consciousness, conscious measurement, and the observer. At neuroscience conferences, discussion started as to whether quantum physics had a place in the communication between nerve cells, and whether the description by classical physics only was insufficient to explain some of the workings of the brain. And after 2000, academic meetings attended by both neuroscientists and quantum physicists started to be held under the title of Quantum Mind/Brain. The speakers at these conferences were not New Age writers or amateurs who ascribe everything to quantum physics; most of them were leading physicists and neuroscientists. What they did and what they wrote was not outside objective scientific practice. NeuroQuantology (2001) is first and foremost a new scientific discipline, just like neuroanatomy (1895), neurobiology (1910), neuroendocrinology, neurochemistry (1920-25), neuropharmacology (1950), neurophilosophy (1989), and neurotheology (1994). It was an approach that blended neuroscience and quantum physics to search with the help of quantum physics for answers to questions which neuroscience alone could not answer. Following the sowing of this first seed, the word NeuroQuantology was used for the first time in 2001, and I became the founder and father first of a journal and then of a potential new field of science. The name was as much a product of inspiration as it was of logic. Of course, there are plenty of clinical and theoretical terms beginning with neuro-, so I was surprised that this particular expression as NeuroQuantology had not been used previously. Up to that time, interdisciplinary articles on neuroscience and related quantum physics had been published in various pioneering physics and neuroscience journals under the heading of “quantum mind/brain”. These were generally articles trying to explain the relationship between measurement and observer problems in quantum physics. Moreover, occasionally, space was given in some cognitive science journals to articles discussing whether quantum physics would solve unanswered questions of free will, choice, decision-making and consciousness. International conferences were organised under the heading of “quantum mind”. But there was no academic journal which covered all such topics. Since 2003, neuroscience and quantum physics have been growing together by examining two main topics under the NeuroQuantology. One of these is the problem of measurement in quantum mechanics. The measurement problem has brought many other still unanswered questions in its train. In classical physics, there is only an observer, but quantum mechanics has become embroiled in unending discussion about whether this person is an observer, a participant in the measurement, or even a reporter of the result of the measurement. There is increasing discussion in many articles on whether consciousness operates on measurement, and if it does, to what extent. The Copenhagen interpretation, which has been around since the beginning of quantum mechanics, while suggesting solutions to multiple worlds and the theory of hidden variables, has not been part of a clear answer to the question of what role the observer plays. Eugene Wigner, John Carew Eccles, David Bohm, Stuart Hameroff, Roger Penrose, Ewan Harris Walker, Henry Stapp, Jack Sarfatti and many other distinguished people have produced mathematical equations or theoretical framework to show the role of consciousness in quantum mechanics, but so far there is no generally accepted approach. If a conscious observer really does have an effect on quantum measurements, many of our equations will have to be drastically changed. The other main topic of NeuroQuantology is quantum neurobiology: that is, the brain operates not only at a classical, macroscopic level, but also at a quantum, microscopic level. It covers the question of where this level begins and whether it has a bearing on our consciousness, mind, memory and decision-making processes. And, last subtopic is quantum biology. Quantum biology refers to applications of quantum mechanics to biological objects and problems. Usually, it is taken to refer to applications of the "non-trivial" quantum features such as superposition, nonlocality, entanglement and tunneling, as opposed to the "trivial" but ubiquitous quantum mechanical nature of chemical bonding, ionization, and other phenomena that are the basis of the fundamental biophysics and biochemistry of organisms. Many biological processes involve the conversion of energy into forms that are usable for chemical transformations and are quantum mechanical in nature. Such processes involve chemical reactions, light absorption, formation of excited electronic states, transfer of excitation energy, and the transfer of electrons and protons (hydrogen ions) in chemical processes such as photosynthesis and cellular respiration. The last decade has produced some significant work showing how quantum effects can occur in biological systems, with advances in three areas utilizing three of the key ideas from quantum physics having been particularly prominent in the media, although often with a certain amount of controversy: superposition in photosynthesis, entanglement in magnetoreception and quantum tunneling in smell perception. The last decade has also seen some significant advances in our understanding of the brain, from research into how quantum computation might create consciousness through coherence in microtubules, to calls for the emergence of a new field of quantum psychiatry/psychopathology to use our understanding of quantum effects in the brain to help tackle mental illness. Discussions focused on the manner in which quantum effects might not just be occurring in the healthy brain, but also creating pathological symptoms, including mental illnesses such as depression and schizophrenia. The first peoples to suggest that quantum mechanics could operate in biology, even though they were the godfathers of quantum mechanics (Niels Bohr, Erwin Schrödinger, Herbert Fröhlich, Walter Heitler, and Max Delbrück), now after 100 years have passed have been squeezed into quantum mechanics and the physics and chemistry of solid, dead matter. Thus, the biological structures that are taught from primary school are made up of physical and chemical structures. Erwin Schrödinger was also one of the first scientists to suggest a study of quantum biology in his 1944 book What Is Life? Incomprehensibly, there has been resistance for a century to quantum biology. NeuroQuantology provides the motivation to break down this resistance and open further a new door to quantum neurobiology.
Introduction to Quantum Biology by Victor Anisimov,James J.P. Stewart Pdf
This book introduces the reader to the theory and methodology of quantum-mechanical modeling of chemical and biological systems. Given the immense complexity of such systems, there is a constant search for new methods. The goal of this text is to derive approximate (semi-empirical) methods to address this class of problems and to provide insight for their continued development. The authors cover such important topics as molecular dynamics, high performance computing, free energy calculations, statistical mechanics, long-range electrostatics, and many-electron systems. They also discuss applications for water salvation, chemical reactions, conformational sampling, and structure relaxation.
Photosynthetic Excitons by Herbert van Amerongen,Leonas Valk?nas,Rienk van Grondelle Pdf
Excitons are considered as the basic concept used by describing the spectral properties of photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light-harvesting antenna and reaction centers. Following the recently obtained structures of a variety of photosynthetic pigment-protein complexes from plants and bacteria our interest in understanding the relation between structure, function and spectroscopy has strongly increased. These data demonstrate a short interpigment distance (of the order of 1 nm or even smaller) and/or a highly symmetric (ring-like) arrangement of pigment molecules in peripheral light-harvesting complexes of photosynthetic bacteria. Books which were devoted to the exciton problem so far mainly considered the spectral properties of molecular crystals. However, the small size of these pigment aggregates in the pigment-protein complexes as well as the role of the protein, which is responsible for the structural arrangement of the complex, clearly will have a dramatic influence on the pigment spectra and exciton dynamics. All these aspects of the problem are considered in this book. Exciton theory is mainly considered for small molecular aggregates (dimers, ring-like structures etc.). Together with the theoretical description of the classical conceptual approach, which mainly deals with polarization properties of the absorption and fluorescence spectra, the nonlinear femtosecond spectroscopy which is widely used for investigations now is also discussed. A large part of the book demonstrates the excitonic effects in a multitude of photosynthetic pigment-protein complexes and how we can understand these properties on the basis of the exciton concept.
