Relativistic Chiral Kinetic Theory from Quantum Field Theories
Yoshimasa Hidaka, Shi Pu, Di-Lun Yang
The chiral kinetic theory of Weyl fermions with collisions in the presence of weak electric and magnetic fields is derived from quantum field theories. It is found that the side-ju…
Lefschetz-thimble approach to the Silver Blaze problem of one-site fermion model
Yuya Tanizaki, Yoshimasa Hidaka, Tomoya Hayata
The sign problem of finite-density QCD at the zero temperature becomes very severe if the quark chemical potential exceeds half of the pion mass. In order to understand its propert…
Kinetic derivation of generalized phase space Chern-Simons theory
Tomoya Hayata, Yoshimasa Hidaka
We study anomalous transport phenomena induced by phase-space Berry curvature. For that purpose we construct a kinetic theory in phase space when all abelian Berry curvatures…
Tetrahedral shape and surface density wave of O caused by -cluster correlations
Yoshiko Kanada-En'yo, Yoshimasa Hidaka
-cluster correlations in the and states of C and O are studied using the method of antisymmetrized molecular dynamics, with which nuclear structure…
Magnetic shift of the chemical freezeout and electric charge fluctuations
Kenji Fukushima, Yoshimasa Hidaka
We discuss the effect of a strong magnetic field on the chemical freezeout points in the ultrarelativistic heavy-ion collision. As a result of the inverse magnetic catalysis or the…
