Short-range excitonic correlations and enhanced excitonic susceptibility in 1T -TiSe
Like other bosons, excitons made of bound electron–hole pairs in solids can condense into a macroscopic quantum state if cooled to a sufficiently low temperature. Although significant progress has been made in observing exciton condensation in engineered low-dimensional systems1,2,3,4,5,6,7,8,9, this exotic phase of matter remains elusive in bulk crystals. The challenge stems from a lack of definitive evidence for the excitonic condensate. In a bulk crystal, ideal superfluidity of the Bose condensate is nearly impossible given the inevitable quasiparticle scattering between the bands that host the electrons and holes10,11. Instead of long-range quantum phase coherence, the condensate is expected to exhibit a spatial density order characterized by a superlattice10, whose period is given by the inverse momentum separation of bound electrons and holes. However, the spatial order is hard to distinguish from conventional density-wave formation in solids, making unambiguous confirmation of exciton condensation in bulk materials particularly difficult. 1T-TiSe2, an excitonic insulator candidate belonging to the family of quasi-two-dimensional transition metal dichalcogenides, exemplifies this challenge of distinguishing between excitonic order and charge-density-wave (CDW) order, which has been debated for over four decades12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30. Key evidence for excitonic condensation was revealed by momentum-resolved electron energy-loss spectroscopy, from which the softening of an...
