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.…
Emergence of Time Semicrystals in Holographic Driven-Dissipative Systems
Yu-Qi Lei, Xian-Hui Ge, Yu Tian +1
Understanding how temporal order degrades in quantum systems remains a central issue in nonequilibrium physics. Here we study the melting of discrete time crystals in a periodicall…
From Quantum Tsallis Entropy to Strange Metals
Xian-Hui Ge
We develop a unified framework connecting quantum Tsallis statistics to electronic transport in strongly interacting systems. Starting from Rényi and Tsallis entropies, we constru…
Lifshitz transition in a holographic finite density flavour brane Weyl semimetal
Cheng-Yuan Lu, Xian-Hui Ge, Sang-Jin Sin
We extend a top-down holographic model of a Weyl semimetal to finite charge density and compute the fermionic spectral function by introducing two probe fermions of opposite chiral…
Hall Angle of a Spatially Random Vector Model
Yi-Li Wang, Young-Kwon Han, Xian-Hui Ge +1
Strange metals exhibit linear resistivity and anomalous Hall transport, yet a comprehensive theory that accounts for both phenomena is still lacking. Recent studies have shown SYK-…
Linear-T Resistivity from Spatially Random Vector Coupling
Yi-Li Wang, Xian-Hui Ge, Sang-Jin Sin
Recently, Patel et al. introduced a higher dimensional version of the SYK model with random coupling in a Yukawa interaction to find the linear- resistivity. We test the univers…
