Two-dimensional Lorentz-violating Chern-Simons-like action
We demonstrate generation of the two-dimensional Chern-Simons-like
Lorentz-breaking action via an appropriate Lorentz-breaking coupling of scalar
and spinor fields at zero as well as at the finite temperature and via the
noncommutative fields method and study the dispersion relations corresponding
to this action.Comment: 10 pages, references added, version accepted to Physics Letters

Quantum-corrected self-dual black hole entropy in tunneling formalism with GUP
In this paper we focus on the Hamilton-Jacobi method to determine the entropy
of a self-dual black hole by using linear and quadratic GUPs(generalized
uncertainty principles). We have obtained the Bekenstein-Hawking entropy of
self-dual black holes and its quantum corrections that are logarithm and also
of several other types.Comment: Latex, 7 pages, no figure. Version to appear in PLB. arXiv admin

Gravitational Aharonov-Bohm effect due to noncommutative BTZ black hole
In this paper we consider the scattering of massless planar scalar waves by a
noncommutative BTZ black hole. We compute the differential cross section via
the partial wave approach, and we mainly show that the scattering of planar
waves leads to a modified Aharonov-Bohm effect due to spacetime
noncommutativityComment: 6 pages, latex, no figures. To appear in PLB. arXiv admin note:
