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-…
