Field Theory On the World Sheet: Mean Field Expansion And Cutoff Dependence
Korkut Bardakci
Continuing earlier work, we apply the mean field method to the world sheet representation of a simple field theory. In particular, we study the higher order terms in the mean field…

Tachyon condensation in boundary string field theory at one loop
K. Bardakci, A. Konechny
We compute the one-loop partition function for quadratic tachyon background in open string theory. Both closed and open string representations are developed. Using these representa…
