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…
Tensor renormalization group and the volume independence in 2D U() and SU() gauge theories
Mitsuaki Hirasawa, Akira Matsumoto, Jun Nishimura +1
The tensor renormalization group method is a promising approach to lattice field theories, which is free from the sign problem unlike standard Monte Carlo methods. One of the remai…
