Quantum Theory Of Tunneling (2nd Edition)
In this revised and expanded edition, in addition to a comprehensible introduction to the theoretical foundations of quantum tunneling based on different methods of formulating and solving tunneling problems, different semiclassical approximations for multidimensional systems are presented. Particular attention is given to the tunneling of composite systems, with examples taken from molecular tunneling and also from nuclear reactions. The interesting and puzzling features of tunneling times are given extensive coverage, and the possibility of measurement of these times with quantum clocks are critically examined.In addition, by considering the analogy between evanescent waves in waveguides and in quantum tunneling, the times related to electromagnetic wave propagation have been used to explain certain aspects of quantum tunneling times. These topics are treated in both non-relativistic as well as relativistic regimes. Finally, a large number of examples of tunneling in atomic, molecular, condensed matter and nuclear physics are presented and solved.
Atom Tunneling Phenomena in Physics, Chemistry and Biology
Atom tunneling phenomena are a new paradigm in the science of materials. This book provides a wealth of interesting information about atom tunneling phenomena in physics, chemistry and biology. Topics include the theory of atom tunneling reactions, conclusive evidence and controlling factors for such reactions in solid hydrogen, tunneling dislocation motion, coherent tunneling diffusion, the production of interstellar molecules and semiconductors using tunneling reactions, the effect of atom tunneling on molecular structure and crystalline structure, the suppression of mutation and cancer by an atom tunneling reaction of vitamin C, and atom tunneling reactions of vitamin E and of enzymes. This book provides graduate students and nonspecialist readers with fascinating insights into the world of atom tunneling phenomena.
Quantum Mechanical Tunneling in Chemical Physics
Quantum mechanical tunneling plays important roles in a wide range of natural sciences, from nuclear and solid-state physics to proton transfer and chemical reactions in chemistry and biology. Responding to the need for further understanding of multidimensional tunneling, the authors have recently developed practical methods that can be applied to
Quantum Tunneling in Complex Systems
In the last two decades remarkable progress has been made in understanding and describing tunneling processes in complex systems in terms of classical trajectories. This book introduces recent concepts and achievements. There is particular emphasis on a dynamical formulation and relations to specific systems in mesoscopic, molecular, atomic and nuclear physics.
Quantum Mechanical Tunnelling And Its Applications
This book presents a new approach to quantum mechanical tunnelling and its applications to various fields of physics. The conventional concepts of this phenomenon, which are based on a time-dependent or time-independent approach, are inadequate in providing explanations for 1) the limit of resolution of field-emission microscope, 2) the Esaki-Integral representation the tunnelling I-V characteristics of tunnel diodes, 3) the Josephson effect, 4) the tunnelling time, etc. The new theory presented here not only provides adequate explanation for all the above-mentioned effects but also gives an accurate expression for tunnelling current density which predicts results closer to the experimentally observed values. The new presentation also provides a more comprehensive description of the results obtained using older treatment.
Resonant Tunneling in Semiconductors
This book contains the proceedings of the NATO Advanced Research Workshop on "Resonant Tunneling in Semiconductors: Physics and Applications", held at Escorial, Spain, on May 14-18, 1990. The tremendous growth in the past two decades in the field of resonant tunneling in semiconductor heterostructures has followed, if not outpaced, the expansion wit nessed in quantum structures in general. Resonant tunneling shares also the multi disciplinary nature of that broad area, with an emphasis on the underlying physics but with a coverage of material systems on the one end and device applications on the other. Indeed, that resonant tunneling provides great flexibility in terms of materials and confi...
Tunneling Phenomena in Chemical Physics
Surveys the contemporary concepts and theoretical and experimental results of tunneling processes. Examines from a unified viewpoint not only chemical reactions but also other physical physicochemical and biological phenomena in which the tunneling effect is of great importance. Covers the general ideas of tunneling, the low temperature chemical reactions that manifest tunneling mechanisms, tunneling effects in amorphous materials, quantum diffusion and surface phenomena in quantum crystals, hopping diffusion and tunneling scavenging of electrons, and tunneling effects in biological systems.
Macroscopic Quantum Tunneling
A coherent and self-contained account of macroscopic quantum phenomena for graduate students and researchers.
Tunneling And Its Implications
"The motion of a particle undergoing quantum tunneling has long been an open and debated problem in several aspects. One of the most discussed is the determination of the time spent in such processes, but many other features deserve consideration. In this volume, both theoretical and experimental aspects, such as quantum measurement, optical analogy, experimental tests, solid state devices and time scale for anomalies (quantum Zeno effect and superluminal evanescence), are explored."--Publisher's website
The Physics and Applications of Resonant Tunnelling Diodes
This book is the first to give a comprehensive description of the physics and applications of resonant tunneling diodes. The opening chapters of the book set out the basic principles of coherent tunneling theory. The authors describe in detail the effects of impurity scattering, femtosecond dynamics, non-equilibrium distribution, and intrinsic bistabilities. They review the applications of RTDs, such as in high-frequency signal generation and multi-valued data storage, and close the book with a chapter on the new field of resonant tunneling through laterally confined zero-dimensional structures. Covering all the key theoretical and experimental aspects of this active area of research, the book will be of great value to graduate students of quantum transport physics and device engineering, as well as to researchers in both these fields.
