Now in its 2nd edition, Quantum Mechanics on the PC presents the most up-to-date approach to elementary quantum mechanics. It is based on the interactive program Interquanta, which runs on MS-DOS either with or without coprocessor (two separate versions included on a 3 1/2'' diskette). With its extensive 3D colour graphics features, the book guides readers through computer experiments on - free particles - bound states and scattering from various potentials - two-particle problems - properties of special functions of mathematical physics. The course, with a wide variety of more than 200 detailed, class-tested problems, provides students - even with little experience in quantum mechanics - with unique practical experience of complex probability amplitudes, eigenvalues, scattering cross sections, and the like. Lecturers and teachers will find here excellent, hands-on classroom demonstrations for their quantum-mechanics course. See LooK 2/92
Readers of the book Quantum Mechanics on the PC by Professors Brandt and Dahmen can now use the programs associated with that book on a Macintosh computer. The diskette provides a complete set of Interquanta programs for computers with or without a mathematics coprocessor.
This book is based on the lecture course "Computer applications in Theo retical Physics", which has been offered at the University of Tiibingen since 1979. This course had as its original aim the preparation of students for a nu merical diploma course in theoretical physics. It soon became clear, however, that the course provides a valuable supplement to the fundamental lectures in theoretical physics. Whereas teaching in this field had previously been prin cipally characterised by the derivation of equations, it is now possible to give deeper understanding by means of application examples. A graphical presen tation of numerical results proves to be important in emphasizing the physics. Interaction with the machine is also valuable. At the end of each calculation the computer should ask the question: "Repeat the calculation with new data (yes/no )?". The student can then answer "yes" and input the new data, e.g. new starting values for position and velocity in solving an equation of motion. The programming of a user-friendly dialogue is not really difficult, but time consuming. At the beginning of the course the student therefore constructs only the numerical parts of the programs. The numerical parts are therefore deleted from the programs under consideration, and newly programmed by the student. Later on, the programming of the graphical output and of the dialogue is taught.Supplementary electronic material no longer available.
Use of this unique book will permit correction of the present defect in quantum education throughout the world. The new breakthrough in quantum mechanics was recently achieved due to the inverse problem approach. It allows finding infinite (!) number of exactly solvable models instead of only about ten previously known. It means an incomparable more convenient basis for the quantum education and countless instructive examples of the precise control of the spectral parameters. That was impossible to imagine in the previous quantum theory. Another great achievement was the discovery of qualitative rules of transformations of the most elementary wave constituents, their separate bumps. This opened the 'black box' of the above mentioned exact models and intensifies many times their usefulness. One acquires the notion about the simplest "bricks" and building blocks of potential and wave transformations. It means a real quantum ABC to acquire the quantum literacy and facilitate the future discoveries. So, one gains the absolutely unexpected ability of immediate prediction how, in principle, to achieve the given properties of the constructed objects. An unprecedented combination of qualitative simplicity and clarity with absolute exactness was achieved. Unlike the numerous books on quantum mechanics, mainly compilations, this one has no analogues. Being first hand information it is utmost intelligible due to computer visualisations. It is not a substitution of the traditional books, but a fundamental, strengthening and simplifying addition to them enlarging and deepening the understanding of the subject instead of previously unintuitive and approximate approach.
Written in an informal yet substantive style that is a joy to read, this book provides a uniquely engaging, in-depth introduction to the concepts of quantum physics and their practical implementation, and is filled with clear, thorough explanations that help readers develop insight into physical ideas and master techniques of problem-solving using quantum mechanics. Fully explores the concepts and strategies of quantum mechanics, showing the connections among the physical concepts that govern the atomic and sub-atomic domain of matter, and examining how these concepts manifest themselves in the mathematical machinery of quantum mechanics. Focuses on the explanations and motivations of the postulates that underlie the machinery of quantum mechanics, and applies simple, single-particle systems in one dimension. Illuminates discussions of ideas and techniques with a multitude of examples that show not just the answers but also the reasoning behind them, and adds dimension to the subject with historical, biographical and philosophical references throughout. Designed for a wide range of readers interested in various branches of physics and engineering physics.
Looks at the scientific breakthroughs in the field of quantum physics, discussing the scientists who made important discoveries, its philosophial implications, and the practical applications of quantum theory.
