Ferroelectric brightening of spin forbidden dark excitons in a WSe2/hybrid perovskite heterostructure
Xinyun Wang, Magdalena Grzeszczyk, Maxim Trushin +14
Long-lived dark excitons in monolayer WSe2 present promising candidates for carrying spin and valley information, but their optical access and spin manipulation have conventionally…

A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…

Observation of excitons bound by antiferromagnetic correlations
Omar Mehio, Yuchen Han, Xinwei Li +4
Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doubl…
