Coupling fundamental quarks to QCD in the dual string representation corresponds to
adding the open string sector. Flavors therefore should be represented by space-time filling …

We study conformal field theories in two dimensions separated by domain walls, which
preserve at least one Virasoro algebra. We develop tools to study such domain walls …

The standard prescription for calculating a Wilson loop in the AdS/CFT correspondence is by
a string world-sheet ending along the loop at the boundary of AdS. For a multiply wrapped …

We find half supersymmetric AdS embeddings in AdS 5× S 5 corresponding to all quarter
BPS orthogonal intersections of D3-branes with Dp-branes. A particular case is the Karch …

Gravity may be``locally localized''over a wide range of length scales on a d-dimensional anti-
de Sitter (AdS) brane living inside AdS d+ 1. In this paper we examine this phenomenon …

We use the holographic proposal for calculating entanglement entropies to determine the
boundary entropy of defects in strongly coupled two-dimensional conformal field theories …

We compute the partition function of the conformal field theory on the two-dimensional
euclidean black hole background using path-integral techniques. We show that the resulting …

We analyze the pair production of charged particles in two-dimensional Anti-de Sitter space
(AdS 2) with a constant, uniform electric field. We compute the production rate both at a semi …

In this work we propose an exact microscopic description of maximally symmetric branes in
a euclidean AdS 3 background. As shown by Bachas and Petropoulos, the most important …

We present a comprehensive analysis of branes in the euclidean 2D black hole (cigar). In
particular, exact boundary states and annulus amplitudes are provided for D0-branes which …
