abstract

We investigate the finite-temperature 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 confinement-deconfinement phase transitions on the $\Omega_I$-$T$ plane, where $\Omega_I$ is the imaginary angular velocity.

  1. Static Quark-Antiquark Interactions Under Rotation

    hep-lat 2026-07 conditional novelty 6.0 of 10

    In quenched SU(3) lattice gluodynamics, imaginary rotation suppresses bare Polyakov free energies above Tc with a bulk shift well fit by A R_xy^2 + B, while the T≈0 static potential shows no significant rotation dependence.

  2. A Chromomagnetic Mechanism for the Rotational Phase Transition of Gluonic Matter

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Using a rotation–magnetic holographic dictionary calibrated to lattice QCD, the paper predicts real rotation raises T_c and induces a negative total moment of inertia in pure gluonic matter near deconfinement.

  3. Gluon polarization contribution to the spin alignment of vector mesons from holography

    hep-ph 2025-01 conditional novelty 6.0 of 10

    A soft-wall holographic QCD model with a rotation-dependent gluon field predicts that rotation enhances the spin alignment of phi and rho mesons at high pT while J/psi stays nearly unaffected.

  4. Imaginary Rotating Gluonic Matter at Strong Coupling

    hep-ph 2025-06 conditional novelty 5.0 of 10

    At strong coupling, imaginary rotation suppresses the Polyakov-loop interaction, so the predicted deconfinement temperature of pure gluonic matter increases with the imaginary angular velocity.

  5. Chromomagnetic Condensate in Finite-Temperature SU(2) Yang-Mills Theory under Imaginary Rotation

    hep-ph 2026-02 conditional novelty 4.0 of 10

    At one loop, imaginary rotation in the SU(2) Savvidy model enhances the chromomagnetic condensate and effective coupling, can suppress the Nielsen-Olesen instability in a finite window, and gives a negative moment-of-...

  6. Chiral vortical catalysis constrained by LQCD simulations

    hep-ph 2024-12 conditional novelty 4.0 of 10

    By fitting an angular-velocity-dependent coupling to LQCD data, the NJL model exhibits chiral vortical catalysis: rotation enhances the chiral condensate and raises the transition temperature and critical endpoint.
