Complex Langevin simulation of quantum vortices in a Bose-Einstein condensate
Tomoya Hayata, Arata Yamamoto
The ab-initio simulation of quantum vortices in a Bose-Einstein condensate is performed by adopting the complex Langevin techniques. We simulate the nonrelativistic boson field the…
Inhomogeneous Polyakov loop induced by inhomogeneous chiral condensates
Tomoya Hayata, Arata Yamamoto
We study the spatial inhomogeneity of the Polyakov loop induced by inhomogeneous chiral condensates. We formulate an effective model of gluons on the background fields of chiral co…
Dispersion relations of Nambu-Goldstone modes at finite temperature and density
Tomoya Hayata, Yoshimasa Hidaka
We discuss the dispersion relations of Nambu-Goldstone (NG) modes associated with spontaneous breaking of internal symmetries at finite temperature and/or density. We show that the…
Schwinger Mechanism with Stochastic Quantization
Kenji Fukushima, Tomoya Hayata
We prescribe a formulation of the particle production with real-time Stochastic Quantization. To construct the retarded and the time-ordered propagators we decompose the stochastic…
