Noncommutativity and discrete physics
نویسنده
چکیده
This paper is an introduction to discrete physics based on a non-commutative calculus of finite differences. This gives a context for the Feynman-Dyson derivation of non-commutative electromagnetism, and for generalizations of this result. The paper discusses these ideas and their relations with quantum groups and topological quantum field theory.

Noncommutativity and Discrete Physics
The purpose of this paper is to present an introduction to a point of view for discrete foundations of physics. In taking a discrete stance, we find that the initial expression of physical theory must occur in a context of noncommutative algebra and noncommutative vector analysis. In this way the formalism of quantum mechanics occurs first, but not necessarily with the usual interpretations. By...
متن کاملUnitary Quantum Physics with Time-Space Noncommutativity
In this work quantum physics in noncommutative spacetime is developed. It is based on the work of Doplicher et al. which allows for time-space noncommutativity. The Moyal plane is treated in detail. In the context of noncommutative quantum mechanics, some important points are explored, such as the formal construction of the theory, symmetries, causality, simultaneity and observables. The dynami...
متن کاملOn Time-Space Noncommutativity for Transition Processes and Noncommutative Symmetries
We explore the consequences of time-space noncommutativity in the quantum mechanics of atoms and molecules, focusing on the Moyal plane with just time-space noncommutativity ([x̂μ, x̂ν ] = iθμν , θ0i ≡/ 0, θij = 0). Space rotations and parity are not automorphisms of this algebra and are not symmetries of quantum physics. Still, the spectral degeneracies of a time-independent Hamiltonian due to s...
متن کاملGlueball mass spectra for supergravity duals of noncommutative gauge theories
We derive the glueball masses in noncommutative super Yang–Mills theories in four dimensions via the dual supergravity description. The spectrum of glueball masses is discrete due to the noncommutativity and the glueball masses are proportional to the noncommutativity parameter with dimension of length. The mass spectrum in the WKB approximation closely agrees with the mass spectrum in finite t...
متن کاملSpace-Time Noncommutativity, Discreteness of Time and Unitarity
Violation of unitarity for noncommutative field theory on compact spacetimes is considered. Although such theories are free of ultraviolet divergences, they still violate unitarity while in a usual field theory such a violation occurs when the theory is nonrenormalizable. The compactness of space-like coordinates implies discreteness of the time variable which leads to appearance of unphysical ...
