Maths HEP Lunchtime Seminars: Quantum Phases of k-strings

Presented by Prem Kumar, Swansea University

5 March 2010 13:00 in CM221

We study the dynamics of confining "k-strings" in a theory obtained by a mass deformation of the N=4 SYM theory with SU(N) gauge group. We review the world-sheet dynamics induced on these strings from the perspective of the gauge theory and its large-N string dual. In particular we argue that confined states of the gauge theory appear as solitons of the k-string world-sheet theory. This latter theory is shown to interpolate between three distinct phases, two of which are separated by a Kosterlitz-Thouless transition induced by condensation of vortex-merons on the world-sheet.
