Gauge Theories with Time Dependent Couplings and their Cosmological Duals
Adel Awad, Sumit R. Das, Suresh Nampuri +2
We consider the N=4 SYM theory in flat 3+1 dimensional spacetime with a time dependent coupling constant which vanishes at , like . In an analogous quantum mecha…
On The Stability of Non-Supersymmetric Attractors in String Theory
Suresh Nampuri, Prasanta K. Tripathy, Sandip P. Trivedi
We study non-supersymmetric attractors obtained in Type IIA compactifications on Calabi Yau manifolds. Determining if an attractor is stable or unstable requires an algebraically c…
Comments on the Spectrum of CHL Dyons
Atish Dabholkar, Davide Gaiotto, Suresh Nampuri
We address a number of puzzles relating to the proposed formulae for the degeneracies of dyons in orbifold compactifications of the heterotic string to four dimensions with …
Spectrum of Dyons and Black Holes in CHL orbifolds using Borcherds Lift
Atish Dabholkar, Suresh Nampuri
The degeneracies of supersymmetric quarter BPS dyons in four dimensions and of spinning black holes in five dimensions in a CHL compactification are computed exactly using Borcherd…
