Two new preprints from our work on epitaxial van der Waals heterostructures: arxiv.org/abs/2506.01470 shows excitons aren't required to drive the charge-density wave phase transition in TiSe2, and arxiv.org/abs/2506.00449 reveals signatures of moiré lattice formation in NbSe2-based heterostructures.
Persistence of charge ordering instability to Coulomb engineering in the excitonic insulator candidate TiSe$_2$
TiSe$_2$ 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 be expected, while a...
