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…
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…
Non-local interactions and supersolidity of moiré excitons
Aleksi Julku
Heterobilayer transition metal dichalcogenide (TMDC) moiré systems provide an ideal framework to investigate strongly correlated physics. Here we theoretically study bosonic many-b…
Nonlinear optical response of resonantly driven polaron-polaritons
Aleksi Julku, Miguel. A. Bastarrachea-Magnani, Arturo Camacho-Guardian +1
Exciton polaritons in two-dimensional semiconductors inside microcavities are powerful platforms to explore hybrid light-matter quantum systems. Here, we study a macroscopic cohere…
Superfluid weight and Berezinskii-Kosterlitz-Thouless transition temperature of twisted bilayer graphene
Aleksi Julku, Teemu J. Peltonen, Long Liang +2
We study superconductivity of twisted bilayer graphene with local and non-local attractive interactions. We obtain the superfluid weight and Berezinskii-Kosterlitz-Thouless (BKT) t…
