چکیده
We use gauge theory/string theory correspondence to study bulk viscosity of strongly coupled mass deformed SU(Nc) N = 4 supersymmetric Yang-Mills plasma, also known as N = 2 gauge theory. For a wide range of masses we confirm the bulk viscosity bound proposed in [1]. For certain choice of masses, the theory undergoes a phase transition with divergent specific heat cV ∼ |1 − Tc/T |−1/2. We show that, although bulk viscosity rapidly grows as T → Tc, it remains finite in the vicinity of the critical point.

We use a low-energy effective description of gauge theory/string theory duality to argue that the Kovtun-Son-Starinets viscosity bound is generically violated in superconformal gauge theories with non-equal central charges c 6= a. We present new examples (of string theory constructions and of gauge theories) where the bound is violated in a controllable setting. We consider the comparison of re...

We obtain a large class of smooth Lorentzian p-brane wormholes in supergravities in various dimensions. They connect two asymptotically flat spacetimes. In cases where there is no dilaton involved in the solution, the wormhole can connect an AdSn × Sm in one asymptotic region to a flat spacetime in the other. We obtain explicit examples for (n,m) = (4, 7), (7, 4), (5, 5), (3, 3), (3, 2). These ...

We systematically formulate a hierarchy of isospectral Hamiltonians in onedimensional supersymmetric quantum mechanics on an interval and on a circle, in which two successive Hamiltonians form N = 2 supersymmetry. We find that boundary conditions compatible with supersymmetry are severely restricted. In the case of an interval, a hierarchy of, at most, three isospectral Hamiltonians is possible...
