Equilibration in a chiral Luttinger liquid
I. V. Protopopov, D. B. Gutman, A. D. Mirlin
We explore the weak-strong-coupling Bose-Fermi duality in a model of a single-channel integer or fractional quantum Hall edge state with a finite-range interaction. The system is d…
Half-integer quantum Hall effect of disordered Dirac fermions at a topological insulator surface
E. J. König, P. M. Ostrovsky, I. V. Protopopov +3
The unconventional (half-integer) quantum Hall effect for a single species of Dirac fermions is analyzed. We discuss possible experimental measurements of the half-integer Hall con…
Density of states in a two-dimensional chiral metal with vacancies
P. M. Ostrovsky, I. V. Protopopov, E. J. König +3
We study quantum interference effects in a two-dimensional chiral metal (bipartite lattice) with vacancies. We demonstrate that randomly distributed vacancies constitute a peculiar…
Relaxation in Luttinger liquids: Bose-Fermi duality
I. V. Protopopov, D. B. Gutman, A. D. Mirlin
We explore the life time of excitations in a dispersive Luttinger liquid. We perform a bosonization supplemented by a sequence of unitary transformations that allows us to treat th…
