We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

This review article provides a pedagogical introduction into various classes of chiral string
compactifications to four dimensions with D-branes and fluxes. The main concern is to …

We propose an explanation via string theory of the correspondence between the Coulomb
branch of certain three-dimensional supersymmetric gauge theories and certain moduli …

A bstract A Page curve for an evaporating black hole in asymptotically flat spacetime is
computed by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically …

In these lecture notes we first assemble the basic ingredients of supersymmetric gauge
theories (particularly N= 4 super-Yang-Mills theory), supergravity, and superstring theory …

A long-standing puzzle about the heterotic string has been what happens when an instanton
shrinks to zero size. It is argued here that the answer at the quantum level is that an extra SU …

A bstract It was recently shown that the theory obtained by deforming a general two
dimensional conformal theory by the irrelevant operator\(T\overline {T}\) is solvable. In the …

We study the conformal field theory of the D1/D5 system compactified on X (X is T 4 or K3). It
is described by a sigma model whose target space is the moduli space of instantons on X …

We review the status of solitons in superstring theory, with a view to understanding the
strong coupling regime. These solitonic solutions are non-singular field configurations which …
