Abstract

We investigate the finite-temperature quantum chromodynamics (QCD) on a rotating lattice with Nf=2+1N_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 confinement-deconfinement phase transitions on the ΩI\Omega_I-TT plane, where ΩI\Omega_I is the imaginary angular velocity.
