General Properties of Noncommutative Field Theories
In this paper we study general properties of noncommutative field theories obtained from the Seiberg-Witten limit of string theories in the presence of an external B-field. We analyze the extensionExpand

Comments on noncommutative gravity
Abstract We study the possibility of obtaining noncommutative gravity dynamics from string theory in the Seiberg–Witten limit. We find that the resulting low-energy theory contains more interactionExpand

On nonanticommutative N = 2 sigma-models in two dimensions
We study nonanticommutative deformations of N = 2 two-dimensional eu- clidean sigma models. We flnd that these theories are described by simple deformations of Zumino's lagrangian and the holomorphicExpand

Constraints on hidden photons from current and future observations of CMB spectral distortions
A variety of beyond the standard model scenarios contain very light hidden sector U(1) gauge bosons undergoing kinetic mixing with the photon. The resulting oscillation between ordinary and hiddenExpand

Critical formation of trapped surfaces in the collision of gravitational shock waves
We study the formation of marginally trapped surfaces in the head-on collision of two shock waves both in anti-de Sitter and Minkowski space-time in various dimensions as a function of the spread ofExpand

Variations on Kaluza-Klein cosmology
We investigate the cosmological consequences of having quantum fields living in a space with compactified dimensions. We will show that the equation of state is not modified by topological effectsExpand

On the stringy nature of winding modes in noncommutative thermal field theories
We show that thermal non-commutative field theories admit a version of ``channel duality'' reminiscent of open/closed string duality, where non-planar thermal loops can be replaced by an infiniteExpand

A note on supersymmetric Yang-Mills thermodynamics
The thermodynamics of supersymmetric Yang-Mills theories is studied by computing the two-loop correction to the canonical free energy and to the equation of state for theories with 16, 8 and 4Expand

Open string thermodynamics and D-branes
Abstract We study the thermodynamics of open superstrings in the presence of p -dimensional D-branes. mWe get some finite temperature dualities relating the one-loop canonical free energy of openExpand
