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…
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…
A new technique to incorporate multiple fermion flavors in tensor renormalization group method for lattice gauge theories
Atis Yosprakob, Jun Nishimura, Kouichi Okunishi
We propose a new technique to incorporate multiple fermion flavors in the tensor renormalization group method for lattice gauge theories, where fermions are treated by the Grassman…
A new picture of quantum tunneling in the real-time path integral from Lefschetz thimble calculations
Jun Nishimura, Katsuta Sakai, Atis Yosprakob
It is well known that quantum tunneling can be described by instantons in the imaginary-time path integral formalism. However, its description in the real-time path integral formal…
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 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…
