Superfluid-Insulator transition of quantum Hall domain walls in bilayer graphene
Victoria Mazo, Chia-Wei Huang, Efrat Shimshoni +2
We consider the zero-filled quantum-Hall ferromagnetic state of bilayer graphene subject to a kink-like perpendicular electric field, which generates domain walls in the electronic…
Dissipationless kinetics of one dimensional interacting fermions
I. V. Protopopov, D. B. Gutman, M. Oldenburg +1
We study the problem of evolution of a density pulse of one-dimensional interacting fermions with a non-linear single-particle spectrum. We show that, despite non-Fermi-liquid natu…
Transport via double constrictions in integer and fractional topological insulators
Chia-Wei Huang, Sam T. Carr, Dmitri Gutman +2
We study transport properties of the helical edge states of two-dimensional integer and fractional topological insulators via double constrictions. Such constrictions couple the up…
Thermally activated recovery of electrical conductivity in LaAlO3/SrTiO3
Snir Seri, Moty Schultz, Lior Klein
Patterned structures of LaAlO3/SrTiO3 that exhibit a decrease in their electrical conductivity below 30 K, recover their higher conductivity upon warming in a thermally activated p…
