1. Complex Langevin calculations in finite density QCD at large μ/T with the deformation technique / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
It is well known that investigating QCD at finite density by standard Monte Carlo methods is extremely difficult due to the sign problem. [...]

2. Testing the criterion for correct convergence in the complex Langevin method / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
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 weight is not real positive. [...]

3. Justification of the complex Langevin method with the gauge cooling procedure / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
Recently, there has been remarkable progress in the complex Langevin method, which aims to solve the complex action problem by complexifying the dynamical variables in the original path integral. [...]

4. Gauge cooling for the singular-drift problem in the complex Langevin method — a test in Random Matrix Theory for finite density QCD / Nagata, Keitaro ; Nishimura, Jun ; Shimasaki, Shinji
Recently, the complex Langevin method has been applied successfully to finite density QCD either in the deconfinement phase or in the heavy dense limit with the aid of a new technique called the gauge cooling. [...]

6. Probing QCD phase structure using baryon multiplicity distribution / Nakamura, Atsushi ; Nagata, Keitaro
We propose a new method to construct canonical partition functions of quantum chromodynamics (QCD) from net number distributions, such as net baryon, net charge, and net strangeness, by using only the CP symmetry. [...]
