Description
The sign problem has been a major obstacle to first-principles calculations in various important physical systems. The Worldvolume Hybrid Monte Carlo (WV-HMC) method [Fukuma-Matsumoto 2020] may be a promising method towards solving the sign problem due to its versatility, reliability and low numerical cost. In this talk, I would like to report recent results on the application of the WV-HMC method to dynamical fermion systems. The emphasis will be on the Hubbard model, which is one of the simplest dynamical fermion systems that have the sign problem.
