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…
Kazakov-Migdal model on the Graph and Ihara Zeta Function
So Matsuura, Kazutoshi Ohta
We propose the Kazakov-Migdal model on graphs and show that, when the parameters of this model are appropriately tuned, the partition function is represented by the unitary matrix…
Supersymmetric Gauge Theory on the Graph
Kazutoshi Ohta, So Matsuura
We consider two-dimensional N=(2,2) supersymmetric gauge theory on discretized Riemann surfaces. We find that the discretized theory can be efficiently described by using graph the…
Commutative Geometry for Non-commutative D-branes by Tachyon Condensation
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…
O(a) Improvement of 2D N=(2,2) Lattice SYM Theory
Masanori Hanada, Daisuke Kadoh, So Matsuura +1
We perform a tree-level O(a) improvement of two-dimensional N=(2,2) supersymmetric Yang-Mills theory on the lattice, motivated by the fast convergence in numerical simulations. The…
Spherical D-brane by Tachyon Condensation
Tsuguhiko Asakawa, So Matsuura
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…
