We study a moving D-brane in a time-dependent background. There is particle production both because of non-trivial cosmological evolution, and by closed string emission from the br…

Extended SL(2,R)/U(1) characters, or modular properties of a simple non-rational conformal field theory
Dan Israel, Ari Pakman, Jan Troost
We define extended SL(2,R)/U(1) characters which include a sum over winding sectors. By embedding these characters into similarly extended characters of N=2 algebras, we show that…
