On the possibility of excitonic phases at the semiconductor–semimetal transition

On the possibility of excitonic phases at the semiconductor–semimetal transition

Motivated by recent experimental evidences for pressure-induced exciton condensation in intermediate valent Tm[Se,Te] compounds, we re-examine, adopting a BEC–BCS crossover scenario, the formation and stability of exciton insulator versus electron–hole liquid phases.
