Finite-temperature spectroscopy in dirty helical Luttinger liquids
ORAL
Abstract
I will discuss a theory of finite-temperature momentum-resolved tunneling spectroscopy (MRTS) for disordered two-dimensional INTERACTING topological-insulator edges. The MRTS setup measures the spectral properties and THUS provides a complementary way (distinct from transport) to characterize helical Luttinger liquid edges of topological insulators. The (exact within bosonization) finite-temperature spectral function and the tunneling current of MRTS are derived in the presence of disorder and interaction. The theory provides a detailed analytical characterization of MRTS between helical edges, that should be of interest for corresponding experimental studies.
