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…

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 highe…

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…
