This book discusses the computational approach in modern statistical physics in a clear yet accessible way, and works out its intimate relations with other approaches in theoretical physics. Individual chapters focus on subjects as diverse as the hard sphere liquid, classical spin models, single quantum particles and Bose-Einstein condensation. They contain in-depth discussions of algorithms ranging from basic enumeration methods to modern Monte Carlo techniques. The emphasis is on orientation. Discussions of implementation details are kept to a minimum. The book heavily relies on illustrations, tables and concise printed algorithms to convey key information: all the material remains easily accessible. The book is fully self-contained: graphs and tables can be readily reproduced by programming at most a few dozen lines of computer code. Most sections lead from an elementary discussion to the rich and difficult problems of contemporary computational and statistical physics, and will be of interest to a wide range of students, teachers and researchers in physics and the neighboring sciences. An accompanying CD allows to incorporate the layout material (illustrations, tables, schematic programs) into the reader's own presentations.

...Fabian enters widely uncharted areas namely the field of human relatedness in politics. It still is extremely uncommon to concretely include factors such as individual and collective unconscious dynamics in political theory and praxeology. At the very beginning of psychoanalysis we find the foundation of healing in both its individual and societal sense in Freud s statement where Id was, I shall be , i.e. where unconsciousness has prevailed consciousness shall dominate. That fundamental process is indeed underlying any positive personal and collective change and it is the definition of what consciousising means (Dr. Albrecht Mahr, Chairman of iFPA). /// ...the reader is taken on a journey into a number of fields of various scientific disciplines a journey which at times becomes a tour de force visiting positivistic science, phenomenology, quantum theory, morphic fields, social psychology as well as peace and conflict studies. Reading this dissertation, the reviewer remains impressed by the massive amount of material the author was able to incorporate. Even more impressive is the originality of the train of thought (Dr. Peter Praxmarer, University of Lugano).

In recent years, progress in nanotechnology has allowed manufacturing of ultra small systems in the areas of electronics and opto-electronics with a high-precision capability of controlling the size and shape. Quantum dots (QD) are typical examples of nanosystems where the electrons are confined in all the 3-dimensions. These quasi-zero-dimensional systems show exotic electronic behaviors typical of the atom like discrete density of states (DOS) of the carriers. QDs could incorporate dopant impurities as a crucial ingredient for their proper functioning. The great interest for understanding the properties of these impurity containing systems comes from the fact that the impurity modifies the energy levels of the materials and in turn affects their electronic and optical properties. So these systems have potential use in electro-optical devices. In this book we explore the excitation kinetics of a repulsive impurity doped quantum dot owing to the time-variation of several impurity parameters e.g. impurity coordinate, impurity domain, and impurity potential. The investigation reveals the sensitivity of the interplay between the above parameters that ultimately shapes the kinetics.

In earlier work, it has been shown that Frobenius algebras with certain properties can be used to simulate classical data. They are especially useful because in their definition itself they incorporate the biggest difference between classical and quantum data- which is the absence of copying and deleting operations for arbitrary quantum states. In later work, it has been shown that a special, commutative, dagger-Frobenius algebra (classical structure) corresponds to an orthonormal basis for a finite- dimensional Hilbert Space. In this paper, we show how classical structures can be used to axiomatize maximally entangled states for two qubits. We then go on explain how this new representation of quantum informatic related protocols using classical structures can be used to encode the flow of quantum data. We explain how this process encodes all the possible observational branches simultaneously, and thus has the ability to tell us the end result that can be achieved in any particular protocol. We end with a summary of the results obtained, and suggestions for future work.

Continued miniaturization of bulk silicon CMOS transistors is being limited by degrading short channel effects.However, these techniques are rapidly approaching material and process limits. Alternate transistor architectures such as the planar ultra-thin body (UTB) FET and double-gate MOSFET may be necessary to continue gate length scaling down to the sub-10nm regime but these structures incorporate with complex quantum physical effects. In this work the optimization and design of advanced FD SOI MOSFET structure has been done. For the optimization, concept of strained silicon, to enhance the current driving capability, and ground plane (GP), to reduce the leakage, have been deployed.Design of conventional FD SOI MOSFET, strained FD SOI MOSFET and strained GPS/GPB FD SOI MOSFET has been made at two technology nodes, 25nm and 32 nm. Device design and simulation of the above structures has been carried out using the ATLAS framework of SILVACO TCAD Tool. By the use of GP, leakage has been reduced in the conventional FD SOI MOSFET but the down side is that drive current has also been decreased. In order to improve the drive current strained silicon has been Deployed.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Stochastic partial differential equations (SPDEs) are similar to ordinary stochastic differential equations. They are essentially partial differential equations that have additional random terms. They can be exceedingly difficult to solve. However, they have strong connections with quantum field theory and statistical mechanics. A stochastic differential equation (SDE) is a differential equation in which one or more of the terms is a stochastic process, thus resulting in a solution which is itself a stochastic process. SDE are used to model diverse phenomena such as fluctuating stock prices or physical system subject to thermal fluctuations. Typically, SDEs incorporate white noise which can be thought of as the derivative of Brownian motion (or the Wiener process), however, it should be mentioned that other types of random fluctuations are possible, such as jump processes.

Modern physics is the post-Newtonian conception of physics. It implies that classical descriptions of phenomena are lacking, and that an accurate, "modern", description of nature requires theories to incorporate elements of quantum mechanics or Einsteinian relativity, or both. In general, the term is used to refer to any branch of physics either developed in the early 20th century and onward, or branches greatly influenced by early 20th century physics. Small velocities and large distances is usually the realm of classical physics. Modern physics, however, often involves extreme conditions: quantum effects typically involve distances comparable to atoms (roughly 10 nanometer), while relativistic effects typically involve velocities comparable to the speed of light (roughly 3000000000 m/s). In general, quantum and relativistic effects exist across all scales, although these effects can be very small in everyday life.

Over the last two decades the atomic coherence and quantum interference were extensively used in high resolution laser spectroscopy. As a matter of fact a new branch of spectroscopy, termed as coherent optical spectra has been emerged to incorporate phase dependent effects on the spectral lines, as well as various nonlinear absorption processes. Apart from spectroscopic point of view, the coherency effects for some fascinating counter intuitive quantum optical phenomena, regarding wave propagation and hence on the control of optical properties of the medium is an active research subject. This book presents an analytical treatment for investigating the coherent effects in the domain of semiclassical atom-field interaction. Under the density matrix formalism different types of systems are considered to study the coherent lineshape and hence various quantum optical phenomena. In particular the influence of the closely spaced transitions on the quantum coherence and hence the subsequent effects are analyzed. The analysis should help and encourage the students of physics as well as potential readers, who want to pursue Quantum Optics in post graduate or research level.

A classical field theory is a physical theory that describes the study of how one or more physical fields interact with matter. The word 'classical' is used in contrast to those field theories that incorporate quantum mechanics (quantum field theories). A physical field can be thought of as the assignment of a physical quantity at each point of space and time (usually in a continuous manner). For example, on weather forecasts, the wind velocity during a day over a country is described by assigning a vector at each point of space (with moving arrows representing the change in wind velocity during the day). From the mathematical viewpoint, classical fields are described by sections of fiber bundles (covariant classical field theory). The term 'classical field theory' is commonly reserved for describing those physical theories that describe electromagnetism and gravitation, two of the fundamental forces of nature. Descriptions of physical fields were given before the advent of relativity theory and then revised in light of this theory. Consequently, classical field theories are usually categorised as non-relativistic and relativistic.
