On Type IIA String Theory on the PP-wave Background
We study type IIA superstring theory on a PP-wave background with 24 supercharges. This model can exactly be solved and then quantized. The open string in this PP-wave background is also studied. We observe that the theory ...
One-Loop Perturbative Corrections to non(anti)commutativity Parameter of N=1/2 Supersymmetric U(N) Gauge Theory
Perturbative corrections to N=1/2 supersymmetric U(N) gauge theory at one-loop order are studied. It is shown that whereas the quantum corrections to N=1 sector of the theory are not affected by the C-deformation, the ...
R^4 Corrections to D1D5p Black Hole Entropy from Entropy Function Formalism
We show that in IIB string theory and for D1D5p black holes in ten dimensions the method of entropy function works. Despite the more complicated Wald formula for the entropy of D1D5p black holes in ten dimensions, their ...
Toroidal Solutions in Horava Gravity
Recently a new four-dimensional nonrelativistic renormalizable theory of gravity was
proposed by Hoˇrava. This gravity reduces to Einstein gravity at large distances. In this
paper we present different toroidal ...
D-brane dynamics in RR deformation of NS5-branes background and tachyon cosmology
We study D-brane dynamics in the gravity dual background of ODp theories using the effective action on the worldvolume of the brane. We explore the similarities of the system with the rolling tachyon, including the exponential ...
Braneworld inflation
We discuss various realizations of the four dimensional braneworld inflation in warped geometries of string theory. In all models the inflaton field is represented by a Dp probe brane scalar specifying its position in the ...
Non-relativistic D3-brane in the presence of higher derivative corrections
Using { alpha }^3 terms of type IIB supergravity action we study higher order corrections
to the non-relativistic non-extremal D3-brane. Utilizing the corrected solution
we evaluate corrections to temperature, ...
More on five dimensional EVH black rings
In this paper we continue our analysis of arXiv:1308.1478 and study in detail the parameter space of three families of doubly spinning black ring solutions: balanced black ring, unbalanced ring and dipole-charged balanced ...
Entropy Function for Non-extremal D1D5 and D2D6NS5-branes
We apply the entropy function formalism to non-extremal D1D5 and D2D6NS5-branes whose throat approximation is given by the Schwarzschild black hole in AdS_3\\\\\\\\\\\\\\\\times S^3\\\\\\\\\\\\\\\\times T^4 and ...
Holographic two-point functions in conformal gravity
In this paper we compute the holographic two-point functions of four dimensional conformal gravity. Precisely we calculate the two-point functions for Energy- Momentum (EM) and Partially Massless Response (PMR) operators ...
