When the universe is treated as a quantum system, it is described by a wave function. This
wave function is a function not only of the matter fields, but also of spacetime. The no …

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 study aspects of anti-de Sitter space in the context of the Swampland. In particular, we
conjecture that the near-flat limit of pure AdS belongs to the Swampland, as it is necessarily …

A bstract In the Emergence Proposal in Quantum Gravity it is conjectured that all light-
particle kinetic terms are absent in the fundamental ultraviolet theory and are generated by …

The Early Universe has become the standard reference on forefront topics in cosmology,
particularly to the early history of the Universe. Subjects covered include primordial …

Einstein's equations stem from General Relativity. In the context of Riemannian manifolds,
an independent mathematical theory has developed around them. Recently, it has produced …

The correspondence between supergravity (and string theory) on $ AdS $ space and
boundary conformal field theory relates the thermodynamics of ${\cal N}= 4$ super Yang …

String Theory comprises two volumes which give a comprehensive and pedagogic account
of the subject. Volume 1, first published in 1998, provides a thorough introduction to the …

Due to the failure of thermodynamics for low temperature near-extremal black holes, it has
long been conjectured that a'thermodynamic mass gap'exists between an extremal black …

String theory is one of the most exciting and challenging areas of modern theoretical
physics. This book guides the reader from the basics of string theory to recent developments …
