The existence of a stable critical point, separate from the Gaussian and XY critical points, of the Ginzburg-Landau theory for superconductors, is demonstrated by direct extraction via Monte-Carlo simulations, of a negative anomalous dimension ηφ of a complex scalar field φ forming a dual description of a neutral superfluid. The dual of the neutral superfluid is isomorphic to a charged superflu...

Three dimensional spacelike warped anti-de Sitter space is studied in the context of Einstein theories of gravity and string theory, where there is no gravitational Chern-Simons term in the action. We propose that it is holographically dual to a two-dimensional conformal field theory with equal left and right moving central charges. Various checks of the central charges are offered, based on th...

We consider several orbifold compactifications of M-theory and their corresponding type II duals in two space-time dimensions. In particular, we show that while the orbifold compactification of M-theory on T/J9 is dual to the orbifold compactification of type IIB string theory on T/I8, the same orbifold T /I8 of type IIA string theory is dual to Mtheory compactified on a smooth product manifold...

We study 0-branes in type IIA on T 2 with a background B-field turned on. This enables us to find the matrix model for M-theory on T 2 with a background 3-form potential along the torus and the lightlike circle. The theory is a non-local 2+1 dim SYM theory on a dual T 2 exactly as proposed by Connes,Douglas and Hull. We calculate the radii and the gauge coupling for the SYM on the dual T 2 for ...

Given a limited resource (such as bandwidth or memory) we consider the problem of scheduling requests from clients that are given as groups of non-intersecting time intervals. Each request j is associated with a demand (the amount of resource required), dj , a t-interval , which consists of up to t segments, for some t ≥ 1, and a weight, w(j). A schedule is a collection of requests. It is feasi...
