Analyzing the two-dimensional doped Hubbard model with the Worldvolume HMC method
Masafumi Fukuma, Yusuke Namekawa
We apply the Worldvolume Hybrid Monte Carlo (WV-HMC) method [arXiv:2012.08468] to the two-dimensional Hubbard model, which is known to suffer from a severe sign problem when the sy…

Applying the Worldvolume Hybrid Monte Carlo method to the Hubbard model away from half filling
Masafumi Fukuma, Yusuke Namekawa
The Worldvolume Hybrid Monte Carlo (WV-HMC) method [arXiv:2012.08468] is an efficient algorithm for addressing the numerical sign problem at moderate computational cost. It mitigat…
