Long lifetimes of spatially indirect excitons (IXs), also known as interlayer excitons, allow
implementing both quantum exciton systems and long-range exciton transport. The van der …

Nonbosonic moiré excitons

TS Huang, P Lunts, M Hafezi - Physical Review Letters, 2024 - APS
Optical excitations in moiré transition metal dichalcogenide bilayers lead to the creation of
excitons, as electron-hole bound states, that are generically considered within a Bose …

Collective excitations of a Bose–Einstein condensate of hard-core bosons and their mediated interactions: from two-body bound states to mediated superfluidity
