Tunneling into strongly biased Tomonaga-Luttinger liquid

Seminar by Alexander Chudnovskiy, 1. Institut für Theoretische Physik, Universität Hamburg, Germany.

Abstract:
We calculate the tunneling density of states for a Tomonaga-Luttinger liquid placed under a strong bias voltage. For the tunneling  through a side-coupled point contact, one can observe the power law singularities in the tunneling density of states separately for the right- and left-movers despite the point-like tunnel contact. Deviations of the nonequilibrium tunneling exponents from the equilibrium case are discussed.
