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.…
Chaotic motion of particles around a Schwarzschild black hole in a swirling electromagnetic background
Wenbin Li, Yu-Qi Lei, Xian-Hui Ge
We investigate the particle motion around a Schwarzschild black hole immersed in a swirling Bertotti-Robinson-Bonnor-Melvin background. This spacetime provides a physically well-mo…
Astrophysically Realistic Secondary Spins Trigger Chaos in Schwarzschild Spacetime and Discernible Gravitational Wave Signatures
Dan-Dan Yuan, Jia-Geng Jiao, Yu-Qi Lei +4
Chaos in extreme-mass-ratio inspirals is often thought to require unrealistically large secondary spins, making its astrophysical relevance uncertain. However, we find that chaos p…
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…
Random organization and non-equilibrium hyperuniform fluids on a sphere
Yusheng Lei, Ning Zheng, Ran Ni
Random organizing hyperuniform fluid induced by reciprocal activation is a non-equilibrium fluid with vanishing density fluctuations at large length scales like crystals. Here we e…
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…
Side-wall pressure distribution of granular silos
Yusheng Lei, Qinwei Ma, Qingfan Shi
The side-wall pressure distribution in static silos is an important and open problem related to storage safety of granular materials. Referring to Lvin's theory [Powder Technology…
