Fermionic T-duality in the pp-wave limit
Ilya Bakhmatov, Eoin Ó Colgáin, Hossein Yavartanoo
AdS5 X S5 and its pp-wave limit are self-dual under transformations involving eight fermionic T-dualities, a property which accounts for symmetries seen in scattering amplitudes in…
EVH Black Holes, AdS3 Throats and EVH/CFT Proposal
M. M. Sheikh-Jabbari, Hossein Yavartanoo
Within class of generic black holes there are extremal black holes (with vanishing Hawking temperature T) and vanishing horizon area Ah, but with finite Ah/T ratio,the Extremal Van…
Holographic Renormalization and Stress Tensors in New Massive Gravity
Yongjoon Kwon, Soonkeon Nam, Jong-Dae Park +1
We obtain holographically renormalized boundary stress tensors with the emphasis on a special point in the parameter space of three dimensional new massive gravity, using the so-ca…
Entropy spectra of black holes from resonance modes in scattering by the black holes
Yongjoon Kwon, Soonkeon Nam
Since the Bekenstein's proposal that a black hole has equally spaced area spectrum, the quasinormal modes as the characteristic modes of a black hole have been used in obtaining th…
Calculating the partition function of N=2 Gauge theories on and AdS/CFT correspondence
Sangmo Cheon, Hyojoong Kim, Nakwoo Kim
We test the AdS/CFT correspondence by computing the partition function of some quiver Chern-Simons-matter theories on three-sphere. The M-theory backgrounds are of…
Quasi Normal Modes for New Type Black Holes in New Massive Gravity
Yongjoon Kwon, Soonkeon Nam, Jong-Dae Park +1
We obtain the quasi-normal mode frequencies of scalar perturbation on new type black holes in three dimensional new massive gravity. In some special cases, the exact quasi-normal m…
