Degrees of freedom in two dimensional string theory
Sumit R. Das
We discuss two issues regarding the question of degrees of freedom in two dimensional string theory. The first issue relates to the classical limit of quantum string theory. In the…
Folds, Bosonization and non-triviality of the classical limit of 2D string theory
Sumit R. Das, Samir D. Mathur
In the 1-dimensional matrix model one identifies the tachyon field in the asymptotic region with a nonlocal transform of the density of fermions. But there is a problem in relating…
Geometric Entropy of Nonrelativistic Fermions and Two Dimensional Strings
Sumit R. Das
We consider the geometric entropy of free nonrelativistic fermions in two dimensions and show that it is ultraviolet finite for finite fermi energies, but divergent in the infrared…
Quark Confinement and Dual Representation in 2+1 Dimensional Pure Yang-Mills Theory
Sumit R. Das, Spenta R. Wadia
We study the quark confinement problem in 2+1 dimensional pure Yang-Mills theory using euclidean instanton methods. The instantons are regularized and dressed Wu-Yang monopoles. Th…
