Graph Zeta Functions and Wilson Loops in Kazakov-Migdal Model
So Matsuura, Kazutoshi Ohta
In this paper, we consider an extended Kazakov-Migdal model defined on an arbitrary graph. The partition function of the model, which is expressed as the summation of all Wilson lo…

Tsuguhiko Asakawa, Goro Ishiki, Takaki Matsumoto +2
There is a difficulty in defining the positions of the D-branes when the scalar fields on them are non-abelian. We show that we can use tachyon condensation to determine the positi…

We find a novel tachyon condensation which provides a D-brane system with spherical worldvolume in the flat spacetime. The tachyon profile is a deformation of a known D0-brane solu…
