Quantum Mpemba effect in holography
Xian-Hui Ge, Shuta Ishigaki, Yu-Qi Lei +1
We investigate the quantum Mpemba effect in a holographic superfluid, in which states with stronger initial symmetry breaking relax faster toward the symmetry-restored equilibrium.…
Quasi-Normal Modes and Nonlinear Electrodynamics in Black Hole Phase Transitions
Zi-Yu Hou, Yu-Qi Lei, Xian-Hui Ge
We investigate the connection between thermodynamic phase transitions and quasi-normal modes (QNMs) in charged black holes with a positive curvature constant, within the framework…
Thermodynamic Stability Versus Chaos Bound Violation in D-dimensional RN Black Holes: Angular Momentum Effects and Phase Transitions
Yu-Qi Lei, Xian-Hui Ge, Surojit Dalui
We compute the Lyapunov exponents for test particles orbiting in unstable circular trajectories around D-dimensional Reissner-Nordström (RN) black holes, scrutinizing instances of…
Stationary equilibrium of test particles near charged black branes with the hyperscaling violating factor
Yu-Qi Lei, Xian-Hui Ge
We explore the upper bound of the Lyapunov exponent for test particles that maintain equilibrium in the radial direction near the charged black brane with the hyperscaling violatin…
Circular Motion of Charged Particles near Charged Black Hole
Yu-Qi Lei, Xian-Hui Ge
We study the circular motion of charged particles near a charged black hole. The general form of the Lyapunov exponent of charged particles is obtained by using the Jacobian matrix…
