Flux backgrounds in 2D string theory
(2004)We study RR flux backgrounds in two dimensional type 0 string theories. In particular, we study the relation between the 0A matrix model and the extremal black hole in two dimensions. Using T-duality we find a dual flux ...

How Bob Laughlin tamed the giant graviton from Taub-NUT space
(2001)In this paper we show how two dimensional electron systems can be modeled by strings interacting with D-branes. The dualities of string theory allow several descriptions of the system. These include descriptions in terms ...

Invasion of the giant gravitons from anti-de Sitter space
(2000)It has been known for some time that the AdS/CFT correspondence predicts a limit on the number of single particle states propagating on the compact spherical component of the AdS x S geometry. The limit is called the stringy ...

Noncommutative geometry, quantum effects and DBI-scaling in the collapse of D0-D2 bound states
(2006)We study fluctuations of time-dependent fuzzy two-sphere solutions of the non-abelian DBI action of D0-branes, describing a bound state of a spherical D2-brane with N D0-branes. The quadratic action for small fluctuations ...
