Quantum Tunneling in Complex Systems: The Semiclassical Approach by Joachim Ankerhold
English | PDF | 2007 | 220 Pages | ISBN : 3540680748 | 4.2 MB

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 with particular emphasis on a dynamical formulation and relations to specific systems in mesoscopic, molecular, atomic and nuclear physics. Advanced imaginary time techniques, e.g. for decay rates and tunnel splittings, are discussed in the first part. The second part covers current developments for wave-packet tunneling in real-time, and the third part describes thermodynamical and nonequilibrium approaches for barrier transmission in dissipative systems.

Quantum Dynamics of Complex Molecular Systems

Quantum Dynamics of Complex Molecular Systems by David A. Micha, Irene Burghardt
English | PDF (True) | 2007 | 424 Pages | ISBN : 3540344586 | 11.3 MB

Quantum phenomena are ubiquitous in complex molecular systems - as revealed by many experimental observations based upon ultrafast spectroscopic techniques - and yet remain a challenge for theoretical analysis. The present volume, based on a May 2005 workshop, examines and reviews the state-of-the-art in the development of new theoretical and computational methods to interpret the observed phenomena. Emphasis is on complex molecular processes involving surfaces, clusters, solute-solvent systems, materials, and biological systems. The research summarized in this book shows that much can be done to explain phenomena in systems excited by light or through atomic interactions. It demonstrates how to tackle the multidimensional dynamics arising from the atomic structure of a complex system, and addresses phenomena in condensed phases as well as phenomena at surfaces. The chapters on new methodological developments cover both phenomena in isolated systems, and phenomena which involve the statistical effects of an environment, such as fluctuations and dissipation.

Quantum Computing and Quantum Bits in Mesoscopic Systems by A. J. Leggett, B. Ruggiero, P. Silvestrini
English | PDF | 2004 | 264 Pages | ISBN : 0306479044 | 24.1 MB

Quantum information science is a new field of science and technology which requires the collaboration of researchers coming from different fields of physics, mathematics, and engineering: both theoretical and applied. Quantum Computing and Quantum Bits in Mesoscopic Systems addresses fundamental aspects of quantum physics, enhancing the connection between the quantum behavior of macroscopic systems and information theory. In addition to theoretical quantum physics, the book comprehensively explores practical implementation of quantum computing and information processing devices.
On the experimental side, this book reports on recent and previous observations of quantum behavior in several physical systems, coherently coupled Bose-Einstein condensates, quantum dots, superconducting quantum interference devices, Cooper pair boxes, and electron pumps in the context of the Josephson effect. In these systems, the book discusses all required steps, from fabrication through characterization to the final basic implementation for quantum computing.

Optical Cooling Using the Dipole Force

Optical Cooling Using the Dipole Force by André Xuereb
English | PDF | 2012 | 190 Pages | ISBN : 3642297145 | 5.1 MB

This thesis unifies the dissipative dynamics of an atom, particle or structure within an optical field that is influenced by the position of the atom, particle or structure itself. This allows the identification and exploration of the fundamental ‘mirror-mediated’ mechanisms of cavity-mediated cooling leading to the proposal of a range of new techniques based upon the same underlying principles. It also reveals powerful mechanisms for the enhancement of the radiation force cooling of micromechanical systems, using both active gain and the resonance of a cavity to which the cooled species are external. This work has implications for the cooling not only of weakly-scattering individual atoms, ions and molecules, but also for highly reflective optomechanical structures ranging from nanometre-scale cantilevers to the metre-sized mirrors of massive interferometers.

Collisional Narrowing and Dynamical Decoupling in a Dense Ensemble of Cold Atoms by Yoav Sagi
English | PDF | 2012 | 89 Pages | ISBN : 3642296041 | 4.4 MB

Ultra-cold atomic ensembles have emerged in recent years as a powerful tool in many-body physics research, quantum information science and metrology. This thesis presents an experimental and theoretical study of the coherent properties of trapped atomic ensembles at high densities, which are essential to many of the aforementioned applications. The study focuses on how inter-particle interactions modify the ensemble coherence dynamics, and whether it is possible to extend the coherence time by means of external control. The thesis presents a theoretical model which explains the effect of elastic collision of the coherence dynamics and then reports on experiments which test this model successfully in the lab. Furthermore, the work includes the first implementation of dynamical decoupling with ultra-cold atomic ensembles. It is demonstrated experimentally that by using dynamical decoupling the coherence time can be extended 20-fold. This has a great potential to increase the usefulness of these ensembles for quantum computation.

Density Functional Theory: Modeling, Mathematical Analysis, Computational Methods, and Applications by Eric Cancès, Gero Friesecke
English | PDF EPUB (True) | 2023 | 595 Pages | ISBN : 303122339X | 50 MB

Density functional theory (DFT) provides the most widely used models for simulating molecules and materials based on the fundamental laws of quantum mechanics. It plays a central role in a huge spectrum of applications in chemistry, physics, and materials science.Quantum mechanics describes a system of N interacting particles in the physical 3-dimensional space by a partial differential equation in 3N spatial variables. The standard numerical methods thus incur an exponential increase of computational effort with N, a phenomenon known as the curse of dimensionality; in practice these methods already fail beyond N=2.

Quantum Optics and Fundamentals of Physics

Quantum Optics and Fundamentals of Physics by Jan Peřina , Zdeněk Hradil , Branislav Jurčo
English | PDF | 1994 | 351 Pages | ISBN : 0792330005 | 29.9 MB

In last years increasing attention has been again devoted to interpretations of quantum theory. In the same time interesting quantum optical experiments have been performed using nonlinear optical processes, in particular frequency down conversion, which provided new information about nature of a photon on the basis of interference and correlation (coincidence) phenomena. Such single-photon and twin-photon effects of quantum optics provide new point of view of interpretations of quantum theory and new tests of its principles. The purpose of this book is to discuss these questions. To follow this goal we give brief reviews of principles of quantum theory and of quantum theory of measurement. As a fundamental theoretical tool the coherent state technique is adopted based on a general algebraic treatment, including the de­ scription of interaction of radiation and matter. Typical quantum behaviour of physical systems is exhibited by nonclassical optical phenomena, which can be examined using photon interferences and correlations.

Im ersten Band haben wir die Grundlagen der makroskopischen Physik erarbeitet. Ausgan- punkt bildeten einige wenige Postulate oder Erhaltungssätze, wie der Energie- und Impu- erhaltungssatz oder die Erhaltung der elektrischen Ladung. Ein wichtiger Wesenszug war dabei der strenge Determinismus aller Naturvorgänge. Auf Grund der Newtonschen Postulate ist es z. B. möglich, Ort und Impuls eines Teilchens zu einem beliebig gewählten späteren Zeitpunkt vorherzusagen, wenn die auf es wirkenden Kräfte bekannt sind.

Confluence of Cosmology, Massive Neutrinos, Elementary Particles, and Gravitation by Behram N. Kursunoglu, Stephan L. Mintz, Arnold Perlmutter
English | PDF | 2002 | 249 Pages | ISBN : 0306462087 | 4.84 MB

Just before the preliminary program of Orbis Scientiae 1998 went to press the news in physics was suddenly dominated by the discovery that neutrinos are, after all, massive particles. This was predicted by some physicists including Dr. Behram Kusunoglu, who had apaper published on this subject in 1976 in the Physical Review. Massive neutrinos do not necessarily simplify the physics of elementary particles but they do give elementary particle physics a new direction. If the dark matter content of the universe turns out to consist of neutrinos, the fact that they are massive should make an impact on cosmology.
