This research aims to investigate the internal structure and localization of quadrupolar excitons in van der Waals trilayers.
Solving the Bethe-Salpeter equation within a large-scale atomistic framework
Analysis of quadropolar exciton structures at small twist angles
Examination of moiré trapping effects on excitonic phases
Identified two distinct quadrupolar excitons with different symmetries and atomic relaxations
Demonstrated moiré trapping's role in stabilizing excitons in triangular lattices under geometric frustration
Without moiré trapping, quadrupolar excitons transition to anti-parallel dipolar excitons on a bipartite square lattice.

Maity et al. (2026) studied this question.
