Signatures of collective photon emission and ferroelectric ordering of excitons near their Mott insulating state in a WSe/WS heterobilayer
Luka Matej Devenica, Zach Hadjri, Jan Kumlin +11
Spontaneous symmetry breaking, arising from the competition of interactions and quantum fluctuations, is fundamental to understanding ordered electronic phases. Although electrical…

Optical control of valley Zeeman effect through many-exciton interactions
Weijie Li, Xin Lu, Jiatian Wu +1
Charge carriers in two-dimensional transition metal dichalcogenides (TMDs), such as WSe, have their spin and valley-pseudospin locked into an optically-addressable index that i…
Dipolar interactions between field-tuneable, localized emitters in van der Waals heterostructures
