abstract
We study the rotation effects of the hot and dense QCD matter in a non-perturbative regime by the gauge/gravity duality. We use the gravitational model that is designated to match the state-of-the-art lattice data on the thermal properties of (2+1)-flavor QCD and predict the location of the critical endpoint and the first-order phase transition line at large baryon chemical potential without rotation. After introducing the angular velocity via a local Lorentz boost, we investigate the thermodynamic quantities for the system under rotation in a self-consistent way. We find that the critical temperature and baryon chemical potential associated with the QCD phase transition decrease as the angular velocity increases. Moreover, some interesting phenomena are observed near the critical endpoint. We then construct the 3-dimensional phase diagram of the QCD matter in terms of temperature, baryon chemical potential, and angular velocity. As a parallel investigation, we also consider the gravitational model of $SU(3)$ pure gluon system, for which the 2-dimensional phase diagram associated with temperature and angular velocity has been predicted. The corresponding thermodynamic quantities with rotation are investigated.

Spectral Functions of $J/\psi$ Meson in Rotating Thermal Background from Holography
In a rotating thermal medium modeled by soft-wall holography, J/ψ spectral peaks split by −ΩJ_z along the rotation axis and acquire projection-dependent distortions for transverse momentum.

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

Strong Coupling Expansion of Gluodynamics on a Lattice under Rotation
A strong-coupling expansion on a rotating lattice gives a deconfinement temperature that decreases with angular velocity, contradicting lattice QCD simulations, alongside a general thermodynamic formula for the shift.

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

On the origin of mixed inhomogeneous phase in vortical gluon plasma
The authors show that the inhomogeneous confinement/deconfinement phase in rotating gluon plasma is caused by the quadratic magnetovortical coupling of angular velocity to chromomagnetic gluon fields.

Holographic spectral functions of exotic spin-1 mesons
In a soft-wall holographic model with gluon condensate, the π1 hybrid and Zc tetraquark-like ground states both melt below the deconfinement temperature, with Zc melting slightly earlier and a larger condensate delayi...

Scaling functions in the soft-wall AdS/QCD models
Soft-wall AdS/QCD models reproduce mean-field chiral scaling functions and follow a T_c scaling law whose slope, tuned by a modified potential, can approach Dyson-Schwinger results.

Imaginary Rotating Gluonic Matter at Strong Coupling
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.

Critical behavior and critical exponents of rotating QCD matter
In the two-flavor NJL model in mean field, the chiral critical endpoint in the temperature versus angular velocity plane shows standard mean-field exponents: alpha ~ 0, beta ~ 1/2, gamma ~ 1, delta ~ 3.

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

Chiral vortical catalysis constrained by LQCD simulations
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.
