Description
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 coherence while suppressing interlayer excitonic order. We also study how photoexcited electron-hole populations affect the competition between these orders. Together, our results show how optical excitation and cavity coupling can alter the balance between intralayer and interlayer excitonic order in 2D heterostructures.
