QCD on Rotating Lattice with Staggered Fermions
Abstract
We investigate the finitetemperature quantum chromodynamics (QCD) on a rotating lattice with $N_f=2+1$ staggered fermions and the projective plane boundary condition. We observe a negative rotational rigidity (defined in the main text) and a negative quark spin susceptibility associated with the chiral vortical effect. In contrast to most of the effective model predictions, we find that the chiral condensate decreases and the Polyakov loop increases with imaginary rotation, implying a rotational catalysis of chiral symmetry breaking and confinement by real rotation. We determine the phase boundaries for both chiral and confinementdeconfinement phase transitions on the $\Omega_I$$T$ plane, where $\Omega_I$ is the imaginary angular velocity.
