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…
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…
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 construc…
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-…
Holographic fermions in the Dyonic Gubser-Rocha black hole
Cheng-Yuan Lu, Xian-Hui Ge, Sang-Jin Sin
We investigate the fermionic properties of a dyonic Gubser-Rocha model in the context of gauge/gravity duality. This model incorporates both a magnetic field and momentum relaxatio…
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…
Dependence of the critical temperature and disorder in holographic superconductors on superfluid density
Zhenguo Wang, Xian-Hui Ge, Shuta Ishigaki
Recent experiments strongly indicate deep connections between transports of strange metal and high superconductors. For instance, it is known that the dependence of the zero-…
First order phase transition in the D3-D7 model from the point of view of the fermionic spectral functions
Xian-Hui Ge, Shuta Ishigaki, Sang-Jin Sin +1
We consider the D3-D7 model and use the spectral function of a probe fermion on D7 to analyze the first order phase transition from the black-hole embedding phase to another black-…
New black holes with hyperscaling violation and transports of quantum critical points with magnetic impurity
Xian-Hui Ge, Yunseok Seo, Sang-Jin Sin +1
We consider the magneto-transports of quantum matters doped with magnetic impurities near the quantum critical points(QCP). For this, we first find new black hole solution with hyp…
