Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe
Sebastian Buchberger, Yann in 't Veld, Akhil Rajan +11
TiSe has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically…
