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…
Entanglement entropy for pure gauge theories in 1+1 dimensions using the lattice regularization
Sinya Aoki, Etsuko Itou, Keitaro Nagata
We study the entanglement entropy (EE) for pure gauge theories in 1+1 dimensions with the lattice regularization. Using the definition of the EE for lattice gauge theories proposed…
The argument for justification of the complex Langevin method and the condition for correct convergence
Keitaro Nagata, Jun Nishimura, Shinji Shimasaki
The complex Langevin method is a promising approach to the complex-action problem based on a fictitious time evolution of complexified dynamical variables under the influence of a…
Gauge cooling for the singular-drift problem in the complex Langevin method --a test in Random Matrix Theory for finite density QCD
Keitaro Nagata, Jun Nishimura, Shinji Shimasaki
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 techni…
Test for a universal behavior of Dirac eigenvalues in the complex Langevin method
Terukazu Ichihara, Keitaro Nagata, Kouji Kashiwa
We apply the complex Langevin (CL) method to a chiral random matrix theory (ChRMT) at non-zero chemical potential and study the nearest neighbor spacing (NNS) distribution of the D…
