Luttinger-liquid behavior in coupled mirror twin boundaries
ORAL
Abstract
Mirror twin boundaries (MTBs), a type of one-dimensional dislocation defects, have been observed in the transition metal dichalcogenide monolayers. These MTBs are capable of hosting quantum valley Hall edge states with restored inversion symmetry and also show Luttinger-liquid behavior in transport experiments over a significant temperature range. A more recent STM experiment has revealed that the MTB effective length can be as short as a few nanometers. We systematically study the many-body spectrum of such MTB Luttinger liquids and the impact of their couplings.
