Topological Frenkel excitons in 2D molecular crystals
Quentin Stein, Sidhartha Nayak, Song Jiang +7
Collective molecular excitations govern energy transport in light-harvesting and optoelectronic materials. Theory predicts that excitonic band topology can generate edge-confined s…

Momentum-Locked Edge Excitons in 2D Molecular Crystals
Sidhartha Nayak, Alex Boeglin, Quentin Stein +4
In molecular crystals, molecular excitations can hybridize into collective Frenkel excitons. Here we show that doubly degenerate excitations in planar two-dimensional molecular cry…
