Statistical interparticle potential between two anyons.

The density matrix of a two-anyon system is evaluated and used to investigate the “statistical interparticle potential” following the theory of Uhlenbeck. The main purpose is to see how the statistical potential will depend on the fractional statistical parameter α. The result shows that the statistical potential for a two-anyon system with α ≥ 1 2 is always repulsive. For the system with 0 < α...

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

Yang-mills Theories on Noncommutative Space-time

We describe some recent progress in our understanding of Yang-Mills theories formulated on noncommutative spaces and in particular how to formulate the standard model on such spaces The idea that space-time might be noncommutative at short distances is not new but it was taken very seriously recently because noncommutative coordinates were found in a specific limit of string theory. This is nev...

Remarks on Time-Space Noncommutative Field Theories

We propose a physical interpretation of the perturbative breakdown of unitarity in timelike noncommutative field theories in terms of production of tachyonic particles. These particles may be viewed as a remnant of a continuous spectrum of undecoupled closedstring modes. In this way, we give a unified view of the string-theoretical and the fieldtheoretical no-go arguments against time-like nonc...

On Critical Phenomena in a Noncommutative Space

In this paper we demonstrate that coordinate noncommutativity at short distances can show up in critical phenomena through UV-IR mixing. In the symmetric phase of the Landau-Ginsburg model, noncommutativity is shown to give rise to a non-zero anomalous dimension at one loop, and to cause instability towards a new phase at large noncommutativity. In particular, in less than four dimensions, the ...
