Hidden Quantum Geometry in Bilayer Exciton Condensates
Xuzhe Ying, Benjamin T. Zhou
When an electron-doped layer is stacked with a hole-doped layer with approximately equal carrier density, inter-layer Coulomb interaction turns the bilayer system into an exciton c…

Quantum metric driven transition between superfluid and incoherent fluid
Xuzhe Ying, Kangle Li
We study the interplay between repulsive interaction and superfluidity in flat band system. We consider spatially indirect excitons in the Lieb lattice bilayer as an example. We sh…
