Length--Velocity Gauge Equivalence of Quantum Geometric Nonlinear Conductivity
Shakeel Ahmad, Fei Xue
Nonlinear transport has emerged as a sensitive probe of quantum geometry beyond the Berry-curvature physics of linear response. However, the intrinsic second-order dc response rema…

Superconductivity and a van Hove singularity confined to the surface of a topological semimetal
Md Shafayat Hossain, Rajibul Islam, Zi-Jia Cheng +16
The interplay between electronic topology and superconductivity is the subject of great current interest in condensed matter physics. For example, superconductivity induced on the…
