Gauge invariant discretization of Chern-Simons couplings

Kohta Hatakeyama, Matsuo Sato, Gota Tanaka

We discretize Chern-Simons couplings in gauge invariant way. We obtain (p+q)-forms representing Chern-Simons couplings on (p + q)-simplexes from wedge products of p- and q-forms on…

Determination of the CP restoration temperature at in 4D SU(2) Yang-Mills theory through simulations at imaginary

Mitsuaki Hirasawa, Kohta Hatakeyama, Masazumi Honda +3

The 't Hooft anomaly matching condition provides constraints on the phase structure at in 4D SU() Yang-Mills theory. In particular, assuming that the theory is confined an…

Numerical studies on the finite-temperature CP restoration in 4D SU(N) gauge theory at

Akira Matsumoto, Kohta Hatakeyama, Mitsuaki Hirasawa +3

Recent studies on the 't Hooft anomaly matching condition have suggested a nontrivial phase structure in 4D SU() gauge theory at . In the large- limit, it has been found…

A new phase in the Lorentzian type IIB matrix model and the emergence of continuous space-time

Mitsuaki Hirasawa, Konstantinos Anagnostopoulos, Takehiro Azuma +5

The Lorentzian type IIB matrix model is a promising candidate for a non-perturbative formulation of superstring theory. In previous studies, Monte Carlo calculations provided inter…

Relationship between the Euclidean and Lorentzian versions of the type IIB matrix model

Kohta Hatakeyama, Konstantinos Anagnostopoulos, Takehiro Azuma +5

The type IIB matrix model was proposed as a non-perturbative formulation of superstring theory in 1996. We simulate a model that describes the late time behavior of the IIB matrix…

A new technique for solving the freezing problem in the complex Langevin simulation of 4D SU(2) gauge theory with a theta term

Akira Matsumoto, Kohta Hatakeyama, Mitsuaki Hirasawa +4

We apply the complex Langevin method (CLM) to overcome the sign problem in 4D SU(2) gauge theory with a theta term extending our previous work on the 2D U(1) case. The topology fre…
