Phase diagram of 4D SU(3) Yang-Mills theory at via imaginary theta simulations

Akira Matsumoto, Mitsuaki Hirasawa, Jun Nishimura +1

It has been speculated that the CP symmetry of 4D SU(3) Yang-Mills theory at is spontaneously broken in the confined phase, and it is recovered precisely at the deconfining t…

Numerical evidence for a CP broken deconfined phase at in 4D SU(2) Yang-Mills theory through simulations at imaginary

Mitsuaki Hirasawa, Masazumi Honda, Akira Matsumoto +2

We investigate the possibility of the spontaneous breaking of CP symmetry in 4D SU(2) Yang-Mills at , which has recently attracted much attention in the context of the higher-…

Toward tensor renormalization group study of lattice QCD

Atis Yosprakob

The tensor renormalization group is a promising complementary approach to traditional Monte Carlo methods for lattice systems, as it is inherently free from the sign problem. We di…

Tensor renormalization group study of the three-dimensional SU(2) and SU(3) gauge theories with the reduced tensor network formulation

Atis Yosprakob, Kouichi Okunishi

We perform a tensor renormalization group simulation of non-Abelian gauge theory in three dimensions using a formulation based on the `armillary sphere.' In this formulation, matri…

Preconditioned flow as a solution to the hierarchical growth problem in the generalized Lefschetz thimble method

Jun Nishimura, Katsuta Sakai, Atis Yosprakob

The generalized Lefschetz thimble method is a promising approach that attempts to solve the sign problem in Monte Carlo methods by deforming the integration contour using the flow…

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…
