Описание: The modulus and phase degrees-of-freedom of molecular states are examined, the relevant continuity relations are identified, and corresponding contributions to the resultant gradient information are summarised. The geometric and physical factors in contributions to the overall gradient information content in a quantum state are also identified. Following this, a formalism is presented for the one- and two-body density matrices in coordinate space and their Fourier transforms in momentum space of a non-relativistic, self-bound, finite-size quantum system. The formalism based upon the so-called Cartesian representation in quantum mechanics is applied to atomic nuclei with a focus on nucleon momentum distributions which reveal important information on short-range correlations. Next, the authors investigate the problem of preparing a target initial state for a two-level system from a system-environment equilibrium or correlated state by an external field. By using the time evolutions of the population difference, the state trajectory in the Bloch sphere representation, and the trace distance between two reduced system states of the open quantum system, the effect of initial system-environment correlations on the preparation of a system state is studied. The authors also study the role of the density matrix in a cryptographic problem called quantum bit commitment, and show how it can be used as a clue for finding secure quantum bit commitment protocols. In subsequent chapter, optical biostability in ladder-plus-Y double quantum dot structure in a unidirectional ring-cavity was modelled using the density matrix theory in parallel with the momentum matrix elements of each transition, which was used to specify Rabi frequencies. Additionally, the phase transition temperatures of the two-dimensional lattice gas of the basal and prism planes of the wurtzite crystal structure were explored using the density-matrix renormalisation-group method. In the closing chapter, the mathematical methods of the description of the evolution of states of quantum many-particle systems by means of the possible modifications of the density operator are considered.

Описание:

The subject of this book is truly original. By encoding of algebraic equations into graphs--originally a purely pedagogical technique--the exploration of physics and physical chemistry reveals common pictures through all disciplines. The hidden structure of the scientific formalism that appears is a source of astonishment and provides efficient simplifications of the representation of physical laws.

Understanding Physics and Physical Chemistry Using Formal Graphs is organized according to the structures emerging from formal graphs, from simple to elaborate, providing after each series of case studies the theoretical elements necessary for understanding their common features. More than 80 case studies are tackled in domains ranging from translational mechanics to Newtonian gravitation to chemical reactions.

With the help of this new tool, the modeling of physical phenomena becomes a fascinating cross-disciplinary exploration. The graphs encourage a visual, unified comprehension of the relationships between physical concepts and variables, properties, and operators. Out-of-the-box and thought provoking, this book inspires lively discussions and fruitful thinking about the connections between mechanics, chemical reactivity, electrodynamics, thermodynamics, and more.

Harmonic Oscillators and Two-By-Two Matrices in Symmetry Problems in Physics

Описание:

This book consists of the articles published in the special issues of this Symmetry journal based on two-by-two matrices and harmonic oscillators. The book also contains additional articles published by the guest editor in this Symmetry journal. They are of course based on harmonic oscillators and/or two-by-two matrices. The subject of symmetry is based on exactly soluble problems in physics, and the physical theory is not soluble unless it is based on oscillators and/or two-by-two matrices. The authors of those two special issues were aware of this environment when they submitted their articles. This book could therefore serve as an example to illustrate this important aspect of symmetry problems in physics.

Описание: Modern developments of Random Matrix Theory as well as pedagogical approaches to the standard core of the discipline are surprisingly hard to find in a well-organized, readable and user-friendly fashion. The focus is mainly on random matrices with real spectrum.The main guiding threads throughout the book are the Gaussian Ensembles.

Описание: This book addresses the mechanism of enrichment of heavy elements in galaxies, a long standing problem in astronomy. It mainly focuses on explaining the origin of heavy elements by performing state-of-the-art, high-resolution hydrodynamic simulations of dwarf galaxies. In this book, the author successfully develops a model of galactic chemodynamical evolution by means of which the neutron star mergers can be used to explain the observed abundance pattern of the heavy elements synthesized by the rapid neutron capture process, such as europium, gold, and uranium in the Local Group dwarf galaxies. The book argues that heavy elements are significant indicators of the evolutionary history of the early galaxies, and presents theoretical findings that open new avenues to understanding the formation and evolution of galaxies based on the abundance of heavy elements in metal-poor stars.

Описание: cross-disciplinary perspectives of its participants. For example, Marc de Mey, a psychologist, used threedimensional computer graphic ren- dering to reconstruct Masaccio's Trinity, in order to understand this early Renaissance painter's use of perspective; Thomas Hubbard, a photo journalist, engaged the entire audience in interactive image analysis; or Robert Williams, a computer scientist and musician, who performed Mussorgsky's Pictures at an Exhibition on a com- puter assisted classical guitar, demonstrating a guitarist's ability to translate simple gestures for enhanced sonic expression. Each paper in this proceedings is a point on the perceptual hori- zon. Together they form a Gestalt that organizes the visual land- scape, highlighting reconverging paths of art, science, and technology toward a future Renaissance. Just as the fifteenth century Renais- sance painter reinvented the technology of perspective to organize and represent images, future Renaissance communicators will rein- vent computer technology to help us better understand visual reality. This conference would have not been successful without support from a few dedicated individuals. Specifically, I would like to thank Jean Coppola (conference coordinator), the NYC ACM SIGGRAPH board of directors, Dr. Carol Wolf (Chair, Computer Science Depart- ment), Kenneth Norz (Assistant Dean), Dr. Susan Merritt ( Dean, School of Computer Science and Information Systems), and the di- rector and staff of Pace University's Downtown Theater. 1.1 REFERENCES 1] Barlow, H., Blackmore, C., and Weston-Smith, M.
