In quantum theory we get an abstract mathematical image of that quantum space in the form of the complete Dirac bracket, This work in theoretical physics is concerned with developing the theory that incorporates both theory of relativity and quantum mechanics into a consistent mathematical theory. One way to achieve this is to extend the manifold of the theory of relativity into a quantum space through incorporation of the quantum dynamics into that functional space. Quantum topodynamics is the field theory that derives from the topology of the quantum space. Theory of the quantum space is founded on the theory of sets. Commutation relations factor the quantum set into

CIPA Home About CIPA Research Scientific Articles Popular Articles Nature of Mass Origin of Inertia ... Questions and Answers Acceleration through the quantum vacuum results in the appearance of an electromagnetic Rindler flux , a cousin of the well-known Unruh-Davies radiation (see the proposed experiment by SLAC physicist Pisin Chen to measure Unruh-Davies radiation). It appears that the inertia of matter may be due to an electromagnetic drag force caused by the Rindler flux. General relativity predicts that light will follow curved spacetime geodesics in the presence of matter. This creates an identical Rindler flux for an object fixed in a gravitational field as for an accelerating object. In this case the analogous well-known cousin is Hawking radiation. Such an approach to the origin of inertial and gravitational forces would explain why the principle of equivalence exists: both inertial and gravitational mass would be due to the same Rindler flux. Background Fundamental physics comprises the attempt to understand the nature of the stable elementary particles (leptons and quarks), the messenger particles (gauge bosons) which mediate the interactions, and the relationship of the four interactions (electromagnetism, weak, strong and gravitational) to each other. Experiments in which particles are made to collide are consistent with elementary particles being immeasurably small, structureless objects. The upper limit on the collisionally-measured size of the electron, for example, is cm. However modern physics theory no longer views particles as point-like objects. In place of that view, quantum field theory assumes that all of space is filled with a quantum field and interprets all stable particles and the messenger particles as excitations of this field. This has resulted in the "standard model" which can legitimately boast precision of some predicted particle properties to an amazing 13 significant figures, but requires 19 hand-adjusted parameters as basic input. There is also the central problem that quantum theory appears to be fundamentally incompatible with general relativity.

General Computing Terms unified field theory Unified field theory is sometimes called the Theory of Everything (TOE, for short): the long-sought means of tying together all known phenomena to explain the nature and behavior of all matter and energy in existence. In physics, a field refers to an area under the influence of some force, such as gravity or electricity, for example. A unified field theory would reconcile seemingly incompatible aspects of various field theories to create a single comprehensive set of equations. Such a theory could potentially unlock all the secrets of nature and make a myriad of wonders possible, including such benefits as time travel and an inexhaustible source of clean energy, among many others. According to Michio Katu, a theoretical physicist at City College, City University of New York, those in pursuit of a unified field theory seek "an equation an inch long that would allow us to read the mind of God." James Clerk Maxwell proposed the first field theory, for electromagnetism, in the middle of the 1800s. Early in the 20th century, Albert Einstein's general theory of relativity - dealing with gravitation - became the second field theory. The term

Overview An Introduction to Quantum Field Theory is a textbook intended for the graduate course covering relativistic quantum mechanics, quantum electrodynamics, and Feynman diagrams. The authors make this subject accessible through carefully worked examples illustrating the technical aspects of the subject, and intuitive explanations of what is going on behind the mathematics. After presenting the basics of quantum electrodynamics, the authors discuss the theory of renormalization and its relation to statistical mechanics, and introduce the renormalization group. This discussion sets the stage for a treatment of non-Abelian gauge theories and their use in describing the fundamental interactions of elementary particles.

IFH Field Theory or Electromagnetics is a discipline that describes the behaviour of electric and magnetic fields and their sources in a specific environment. This environment can be guiding or radiating structures in a homogeneous or inhomogeneous medium with or without losses. The complexity of today's relevant problems in electromagnetics are such that in most cases analytical solutions to Maxwell's equations are not possible. Thus a continuous physical reality, the electromagnetic field, is represented by a discretized, sampled numerical approximation to replicate the behaviour of the actual problem with appropriate accuracy and resolution. Therefore the discipline of field theory or electromagnetics is nowadays often referred to as computational electromagnetics We hope you will enjoy surfing on our web site and find valuable information on our different research and teaching activities! , head of the Field Theory Group at IFH.

Crystal Field Theory Octahedral Crystal Fields Tetrahedral Crystal Fields Square Planar Complexes The Spectrochemical Series ... High-Spin Versus Low-Spin Octahedral Complexes At almost exactly the same time that chemists were developing the valence-bond model for coordination complexes, physicists such as Hans Bethe, John Van Vleck, and Leslie Orgel were developing an alternative known as crystal field theory . This theory tried to describe the effect of the electrical field of neighboring ions on the energies of the valence orbitals of an ion in a crystal. Crystal field theory was developed by considering two compounds: manganese(II) oxide, MnO, and copper(I) chloride, CuCl. Octahedral Crystal Fields Each Mn ion in manganese(II) oxide is surrounded by six O ions arranged toward the corners of an octahedron, as shown in the figure below. MnO is therefore a model for an octahedral complex in which a transition-metal ion is coordinated to six ligands. What happens to the energies of the 4 s and 4 p orbitals on an Mn ion when this ion is buried in an MnO crystal? Repulsion between electrons that might be added to these orbitals and the electrons on the six O
