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…
Controlling an altermagnetic spin density wave in the kagome magnet CsCr3Sb5
Zihao Huang, Chenchao Xu, Yande Que +8
The interplay of charge and spin orders lies at the heart of correlated electron physics and plays a critical role in the emergence of unconventional quantum phases. Kagome magnets…
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…
A gate-tunable quantum phase transition in a topological excitonic insulator
Yande Que, Yang-Hao Chan, Junxiang Jia +9
Coulomb interactions among electrons and holes in two-dimensional (2D) semimetals with overlapping valence and conduction bands can give rise to a correlated insulating ground stat…
