Excitonic order in quantum materials: fingerprints, platforms and opportunities
Yande Que, Clara Rebanal, Liam Watson +4
The exciton insulator (EI) is a unique many-body ground state of condensed, spontaneously formed excitons (electron-hole pairs) in equilibrium, distinct from conventional band or M…

Observation of charge density wave excitonic order parameter in topological insulator monolayer WTe2
Liam Watson, Joan Ripoll, Zhengjue Tong +12
Strong electron-hole interactions in a semimetal or narrow-gap semiconductor may drive a ground state of condensed excitons. Monolayer WTe2 has been proposed as a host material for…

Reversal of charge transfer doping on the negative electronic compressibility surface of MoS2
Liam Watson, Iolanda Di Bernardo, James Blyth +6
The strong electron-electron interaction in transition metal dichalcogenides (TMDs) gives rise to phenomena such as strong exciton and trion binding and excitonic condensation, as…
