Short-range excitonic correlations and enhanced excitonic susceptibility in 1T-TiSe2

Abstract Excitons—bound states of electrons and holes—can spontaneously condense into a quantum coherent ground state. 1 T -TiSe 2 , a layered transition metal dichalcogenide, is a candidate for realizing this phase in a bulk material, but its putative excitonic condensation is a...
