Dipole condensates in synthetic rank-2 electric fields
Jiali Zhang, Wenhui Xu, Qi Zhou +1
Dipole condensates, formed from particle-hole pairs, represent a unique class of charge-neutral quantum fluids that evade conventional vector gauge fields, making their electrodyna…

Excitonic skin effect
Wenhui Xu, Qi Zhou
We show that strong interactions combined with band-dependent imaginary vector potentials give rise to boundary localization of particle-hole pairs, which we term the excitonic ski…
