28. Poster: Cavity Control and Optical Signatures of the Excitonic Orders in 2D Heterostructures

Chongxiao Fan (phd Student @ Max-Planck Institute for Structure and Dynamics of Matter)

POSTER PRESENTATION
Experiments have provided evidence for interlayer exciton condensation in MoSe₂/WSe₂ atomic double layers. Motivated by this platform, we use a self consistent, material based four band model to investigate how light couples to competing excitonic orders. We examine their dynamics under coherent pumping and find that coupling to an optical cavity favors intralayer...

29. Poster: Valleys, Orbitals and Symmetry in Moiré Matters

Yifan Gao (PostDoc @ Max-Planck Institute for Structure and Dynamics of Matter)

POSTER PRESENTATION
The electronic structure of a moiré material reflects both the valley and orbital character
of its parent layers and the symmetry of the twisted bilayer. First-principles calculations
of twisted WSe₂ show that Γ- and K-derived minibands retain distinct orbital character,
which helps explain their different responses to strain and out-of-plane pressure.
Changes in...
