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:

The entropy of the noncommutative acoustic black hole based on generalized uncertainty principle
In this paper we investigate statistical entropy of a 3-dimensional rotating
acoustic black hole based on generalized uncertainty principle. In our results
we obtain an area entropy and a correction term associated with the
noncommutative acoustic black hole when introduced in the generalized
uncertainty principle takes a specific value. However, in this method, it is
not needed to introduce the ultraviolet cut-off and divergences are eliminated.
Moreover, the small mass approximation is not necessary in the original
brick-wall model.Comment: 9 pages, no figures; version to appear in PLB. arXiv admin note:
