Reproduction of the charge density wave phase diagram in $1T$-${\mathrm{TiSe}}_2$ exposes its excitonic character

Chuan Chen, Bahadur Singh, Hsin Lin +1

Recent experiments suggest that excitonic degrees of freedom play an important role in precipitating the charge density wave (CDW) transition in $1T$-${\mathrm{TiSe}}_2$. Through sys…
