STRINGS IN COSMOLOGICAL SPACETIMES AND THEIR BACK-REACTION

H. J. de Vega

This is a short review on strings in curved spacetimes. We start by recalling the classical and quantum string behaviour in singular plane waves backgrounds. We then report on the…

Simple Approach to Thermal Bethe Ansatz

H. J. de Vega

We report on a new approach to the calculation of thermodynamic functions for crossing-invariant models solvable by Bethe Ansatz. In the case of the XXZ Heisenberg chain we derive,…
