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 …

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 …

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

Heavy ion collision experiments recreating the quark-gluon plasma that filled the nascent
universe have established that it is a nearly perfect liquid that flows with such minimal …

It is shown that low-energy string theory admits a variety of solutions with the structure of an
extended object surrounded by an event horizon. In particular there is a family of black string …

Effective field theories in type I and II superstring theories for D-branes located at points in
the orbifold C^ 2/Z_n are supersymmetric gauge theories whose field content is conveniently …

This is an introduction to the properties of D-branes, topological defects in string theory on
which string endpoints can live. D-branes provide a simple description of various …

We study the quantum-mechanical properties of a supermembrane and examine the nature
of its ground state. A supersymmetric gauge theory of area-preserving transformations …

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 …

Superstring theory has a rich spectrum of solitonic states, and over the last years much has
been learned about their important roles in the theory, in strong-weak coupling duality and in …
