Quantum Geometric Effects on the Higgs Mode in Flat-band Superconductors
Yuhang Xiao, Ning Hao
Flat-band systems are of great interest due to their strong electron correlations and unique band geometry. Recent studies have linked the properties of Cooper pairs in flat-band s…

A generic model with unconventional Rashba bands and giant spin galvanic effect
Xinliang Huang, Yuhang Xiao, Rui Song +1
In two-dimensional system, Rashba spin-orbit coupling can lift spin degeneracy and gives the opposite spin chirality of two split Fermi circles from two Rashba bands. Here, we prop…
