Finite-density lattice QCD and sign problem: current status and open problems
Keitaro Nagata
This an English translation of a review of finite-density lattice QCD. The original version in Japanese appeared in Soryushiron Kenkyu Vol 31 (2020) No. 1.
Complex Langevin calculations in QCD at finite density
Yuta Ito, Hideo Matsufuru, Yusuke Namekawa +4
We demonstrate that the complex Langevin method (CLM) enables calculations in QCD at finite density in a parameter regime in which conventional methods, such as the density of stat…
Complex Langevin calculations in finite density QCD at large with the deformation technique
Keitaro Nagata, Jun Nishimura, Shinji Shimasaki
It is well known that investigating QCD at finite density by standard Monte Carlo methods is extremely difficult due to the sign problem. Some years ago, the complex Langevin metho…
Testing the criterion for correct convergence in the complex Langevin method
Keitaro Nagata, Jun Nishimura, Shinji Shimasaki
Recently the complex Langevin method (CLM) has been attracting attention as a solution to the sign problem, which occurs in Monte Carlo calculations when the effective Boltzmann we…
On the condition for correct convergence in the complex Langevin method
Shinji Shimasaki, Keitaro Nagata, Jun Nishimura
The complex Langevin method (CLM) provides a promising way to perform the path integral with a complex action using a stochastic equation for complexified dynamical variables. It i…
Gauge cooling for the singular-drift problem in the complex Langevin method --- an application to finite density QCD
Keitaro Nagata, Hideo Matsufuru, Jun Nishimura +1
We study full QCD at finite density and low temperature with light quark mass using the complex Langevin method. Since the singular drift problem turns out to be mild on a $4^3 \ti…
