Probing spatially resolved spin density correlations with trapped excitons
Shanshan Ding, Jose Antonio Valerrama Botia, Aleksi Julku +2
The rapidly growing class of atomically thin and tunable van der Waals materials is intensely investigated both in the context of fundamental science and for new technologies. Ther…

Induced Interactions and Bipolarons in Spin-Orbit Coupled Bose-Einstein Condensates
Zhe Yang, Shanshan Ding, Qizhong Zhu
Impurities immersed in a Bose-Einstein condensate (BEC) can interact indirectly through the exchange of Bogoliubov excitations. These impurities, which form dressed quasiparticles…

Exciton interacting with a moiré lattice: Polarons, strings, and optical probing of spin correlations
Aleksi Julku, Shanshan Ding, Georg M. Bruun
We develop a general theory for how an exciton in an atomically thin transition metal dichacogenide (TMD) monolayer couples to spin and charge correlations in an adjacent moire lat…
