Worldvolume tempered Lefschetz thimble method and its error estimation
Masafumi Fukuma, Nobuyuki Matsumoto, Yusuke Namekawa
The worldvolume tempered Lefschetz thimble method (WV-TLTM) is an algorithm towards solving the sign problem, where hybrid Monte Carlo updates are performed on a continuous accumul…
The basics and applications of the tempered Lefschetz thimble method for the numerical sign problem
Masafumi Fukuma, Nobuyuki Matsumoto
The numerical sign problem has long been a major obstacle to first-principles calculations in various important fields of physics. We report that the recently proposed algorithm, t…
Tensor network approach to 2D Yang-Mills theories
Masafumi Fukuma, Daisuke Kadoh, Nobuyuki Matsumoto
We propose a novel tensor network representation for two-dimensional Yang-Mills theories with arbitrary compact gauge groups. In this method, tensor indices are directly given by g…
Statistical analysis method for the worldvolume hybrid Monte Carlo algorithm
Masafumi Fukuma, Nobuyuki Matsumoto, Yusuke Namekawa
We discuss the statistical analysis method for the worldvolume hybrid Monte Carlo (WV-HMC) algorithm [arXiv:2012.08468], which was recently introduced to substantially reduce the c…
