Broken spacetime symmetries and elastic variables
Tomoya Hayata, Yoshimasa Hidaka
We discuss spontaneous breaking of continuum symmetries, whose generators do explicitly depend on the spacetime coordinates. We clarify the relation between broken symmetries and e…
Sign problem and the chiral spiral on the finite-density lattice
Ryutaro Fukuda, Kenji Fukushima, Tomoya Hayata +1
We investigate the sign problem of the fermion determinant at finite baryon density in (1+1) dimensions, in which the ground state in the chiral limit should be free from the sign…
Temporal Chiral Spiral in Strong Magnetic Fields
Tomoya Hayata, Yoshimasa Hidaka, Arata Yamamoto
Vacuum properties of quantum chromodynamics in strong magnetic and finite electric fields are investigated. We show that when a uniform electric field is instantaneously applied in…
Dynamical Mass Generation of Vector Mesons from QCD Trace Anomaly
Tomoya Hayata
Mass formulas for the light-vector mesons written in terms of the gluon condensate i.e., the trace anomaly in quantum chromodynamics (QCD), are derived on the basis of finite energ…
