Matrix model for polyakov loops, string field theory in the temporal gauge and winding string condensations in anti-de sitter space

Closed string field theory is constructed by stochastically quantizing a matrix model for Polyakov loops that describes phases of a large N gauge theory at finite temperature. Coherent states in this string field theory describes winding string condensation which has been expected to cause topology change from thermal AdS geometry to AdSSchwarzschild black hole geometry. D-branes in this closed string field theory is also discussed. Based on a talk given at CosPA 2007, Taipei.
