Robust Luttinger liquid state of 1D Dirac fermions in a van der Waals system Nb${}_9$Si${}_4$Te${}_{18}$

Qirong Yao, Hyunjin Jung, Kijeong Kong +4

We report on the Tomonaga-Luttinger liquid (TLL) behavior in fully degenerate 1D Dirac fermions. A ternary van der Waals material Nb${}_9$Si${}_4$Te${}_{18}$ incorporates in-plane NbTe$_…
