DESCRIPTION:Speakers: 冀翀 杨 (Liaoning normal university)\nAnalytic st
 rong-coupling calculations and previous rotating-lattice simulations appea
 r to predict opposite responses of deconfinement to rotation.  We investig
 ate this tension in pure $SU(3)$ gauge theory on anisotropic lattices at i
 maginary angular velocity over $1.5\\leq\\beta\\leq4.5$.  At strong coupli
 ng we find a reentrant deconfined--confined--deconfined sequence near the 
 zero-rotation transition\, in qualitative agreement with analytic strong-c
 oupling theory.  The corresponding nonmonotonic phase boundary locally con
 tinues to a decreasing transition temperature at real rotation.  As $\\bet
 a$ increases\, the reentrant interval closes between $\\beta=2.75$ and $3.
 0$\; at larger $\\beta$ and moderate temperatures above $T_c^0$\, the Poly
 akov loop instead initially increases with imaginary angular velocity\, re
 covering the response observed in earlier lattice studies.  We further sho
 w that quadratic and quartic fits to the same imaginary-rotation boundary 
 yield opposite trends after analytic continuation.  The results reconcile 
 the strong-coupling and previous lattice observations as distinct coupling
 --temperature regimes and expose the cutoff and ansatz dependence that mus
 t be controlled when extrapolating to real rotation.\n\nhttps://indico.itp
