Matrix Quantum Mechanics and Soliton Regularization of Noncommutative Field Theory [PDF]

open access: green, 2004
We construct an approximation to field theories on the noncommutative torus based on soliton projections and partial isometries which together form a matrix algebra of functions on the sum of two circles.

Noncommutative field theory and composite Fermi liquids in some quantum Hall systems [PDF]

open access: bronze, 2020
Composite Fermi liquid metals arise at certain special filling fractions in the quantum Hall regime and play an important role as parent states of gapped states with quantized Hall response. They have been successfully described by the Halperin-Lee-Read (

ON FINITE NONCOMMUTATIVITY IN QUANTUM FIELD THEORY [PDF]

open access: greenInternational Journal of Modern Physics A, 2010
We consider various modifications of the Weyl–Moyal star-product, in order to obtain a finite range of nonlocality. The basic requirements are to preserve the commutation relations of the coordinates as well as the associativity of the new product.

Noncommutative quantum field theory [PDF]

open access: yesFortschritte der Physik, 2014
AbstractWe summarize our recent construction of the ϕ4‐model on four‐dimensional Moyal space. This is achieved by solving the quartic matrix model for a general external matrix in terms of the solution of a non‐linear equation for the 2‐point function and the eigenvalues of that matrix. The β‐function vanishes identically.

Quantum Hall physics = noncommutative field theory [PDF]

open access: yesJournal of High Energy Physics, 2001
In this note, we study a matrix-regularized version of non-commutative U(1) Chern-Simons theory proposed recently by Polychronakos. We determine a complete minimal basis of exact wavefunctions for the theory at arbitrary level k and rank N and show that these are in one-to-one correspondence with Laughlin-type wavefunctions describing excitations of a ...

Braided quantum electrodynamics

open access: yesJournal of High Energy Physics, 2023
The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

An Introduction to Noncommutative Physics

open access: yesPhysics, 2023
Noncommutativity in physics has a long history, tracing back to classical mechanics. In recent years, many new developments in theoretical physics, and in practical applications rely on different techniques of noncommutative algebras.
