Eurotraps -- A European experiment intended to test the theory of quantum electrodynamics to extremely high accuracy. Exploiting Zero Point Energy -- A Scientific American article outlining the debate on whether an endless source of energy can be found using the zero point energy which appears in field theories. Feynman Diagrams -- A summary of the rules governing the creation of Feynman diagrams. Finite Temperature Quantum Field Theory -- A brief overview of research in QFT at the Imperial College Goldstone Bosons -- These notes review the effective lagrangian treatment of Goldstone and pseudo-Goldstone bosons, taking examples from high-energy/nuclear and condensed-matter physics. Introduction to Seiberg-Witten Theory -- We give an elementary introduction to the recent solution of supersymmetric Yang-Mills theory. In addition, we review how it can be re-derived from string duality. Quantum Field Theory in Curved Spacetime -- These postscript lectures deal with selected aspects of quantum field theory in curved spacetime Quantum Field Theory in Curved Spacetime -- These lectures deal with selected aspects of quantum field theory in curved spacetime including the following topics: (1) Quantization of fields on a curved background, particle creation by gravitational fields, particle creation in an expanding universe; moving mirror radiation. (2) The Hawking effect - particle creation by black holes. (3) Ultraviolet and infrared divergences, renormalization of the expectation value of the stress tensor; global symmetry breaking in curved spacetime. (4) Negative energy in quantum field theory, its gravitational effects, and inequalities which limit negative energy densities and fluxes. (5) The semiclassical theory of gravity and its limitations, breakdown of this theory due to metric fluctuations, lightcone fluctuations. Quantum Fields LLC Research & Development -- Research and Development in Vacuum Fluctuations, Casimir Forces and EPR Entangled States Quantum field theories -- research in the foundations of quantum field theory based on sets, logic, groups and the topology of quantum space Relativistic Quantum Fields I -- The aim of this course is to introduce students to the theory of quantum fields, at a level appropriate for 4th Year MPhys students of physics The Casimir Effect -- What is the Casimir Effect? The Casimir Effect in Relativity -- An explanation of the Casimir effect using general relativity. The State of Matrix Theory -- A set of lecture notes with RealPlayer audio on Matrix Theory Topics in Nonequilibrium Field Theory -- Nonequilibrium field theory covers a variety of topics such as transport theory of quantum fields, nonequilibrium phase transitions, the nucleation and transport of topological defects and other nonlinear coherent structures, as well as fundamental issues such as the quantum-classical transition and the coherent control of quantum systems. Virtual Particles -- A short article from USENET Physics FAQ. Warren Seigel -- a Professor at C.N. Yang Institute for Theoretical Physics, State University of New York, Stony Brook, Long Island, he''s not content just to study the relationships between string theory and particle theory, but also to write goofy essays, and maintain this Web site.
