Excitonic insulator in bulk MoS2 under pressure

Cnr-Nano Modena researchers predict the possibility of observing – experimentally and unambiguously – an excitonic insulator in bulk molybdenum disulfide, at pressure and temperature accessible in a lab facility. The result of this computational work provides a strategy to experimentally realize a such elusive state, which promises to have a significat impact in future quantum technologies. The study, in collaboration with the University of Modena and Reggio Emilia, is published in PNAS journal.
