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…
Platforms for the realization and characterization of Tomonaga-Luttinger liquids
Isabelle Bouchoule, Roberta Citro, Tim Duty +5
The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…
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…
