Geometric origin of supercurrents in Berry phase: Formula for computing currents from wavefunctions with correlation and particle number variation
B. Q. Song, J. D. H. Smith, J. Wang
The paper presents a phase‑based formula that computes supercurrents directly from microscopic BCS wavefunctions, incorporating Berry‑phase derived group velocity and a correlation…

Quantum geometry embedded in unitarity of evolution: revealing its impacts as geometric oscillation and dephasing in spin resonance and crystal bands
B. Q. Song, J. D. H. Smith, T. Jiang +2
Quantum Hall effects provide intuitive ways of revealing the topology in crystals, i.e., each quantized "step" represents a distinct topological state. Here, we seek a counterpart…
