Classical and Quantum Branes in c=1 String Theory and Quantum Hall Effect

Alexey Boyarsky, Bogdan Kulik, Oleg Ruchayskiy

Interpretation of D1 and D0-branes in 1+1 string theory as classical and quantum eigen-values in dual c=1 Matrix Quantum Mechanics (MQM) was recently suggested. MQM is known to be…

De Sitter vacua from N=2 gauged supergravity

Klaus Behrndt, Swapna Mahapatra

Typical de Sitter (dS) vacua of gauged supergravity correspond to saddle points of the potential and often the unstable mode runs into a singularity. We explore the possibility to…

Multi-spin strings on AdS(5)xT(1,1) and operators of N=1 superconformal theory

Nakwoo Kim

We study rotating strings with multiple spins in the background of , which is dual to a superconformal field theory with global symmetry $SU(2)…

Bulk Witten Indices from D=10 Yang Mills Integrals

Thomas Fischbacher

Values for the bulk Witten indices for D=10 Yang-Mills integrals for some regular simple groups of rank 4 and 5 are calculated by employing the BRST deformation technique by Moore,…

Symmetry breaking, permutation D-branes on group manifolds: boundary states and geometric description

Gor Sarkissian, Marija Zamaklar

We use the permutation symmetry between the product of several group manifolds in combination with orbifolds and T-duality to construct new classes of symmetry breaking branes on p…

Chronological structure of a Goedel type universe with negative cosmological constant

Klaus Behrndt, Markus Pössel

We show that the Goedel solution of five-dimensional gauged supergravity contains either closed time-like curves through every space-time point or none at all, dependent on the rot…
