Chirality in curved polyaromatic systems
WebDec 20, 2024 · Physically, the boundary of the DSI can be understood as the onset of synchronization between DM and SM. Such a synchronization process is the result of a dissipation-induced level attraction, a hallmark of non-Hermitian systems ( 29, 30 ).
