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…
Multifractality and electron-electron interaction at Anderson transitions
I. S. Burmistrov, I. V. Gornyi, A. D. Mirlin
Mesoscopic fluctuations and correlations of the local density of states are studied near metal-insulator transitions in disordered interacting electronic systems. We show that the…
Hydrodynamics in graphene: Linear-response transport
B. N. Narozhny, I. V. Gornyi, M. Titov +2
We develop a hydrodynamic description of transport properties in graphene-based systems which we derive from the quantum kinetic equation. In the interaction-dominated regime, the…
Quantum interference in HgTe structures
I. V. Gornyi, V. Yu. Kachorovskii, A. D. Mirlin +1
We study quantum transport in HgTe/HgCdTe quantum wells under the condition that the chemical potential is located outside of the bandgap. We first analyze symmetry properties of t…
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…
