Fractionalized double quantum wires — •Tobias Meng1,2 and Eran Sela31Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden, Germany — 2Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland — 3Raymond and Beverly Sackler School of Physics and Astronomy, Tel-Aviv University, Tel Aviv, 69978, Israel

We discuss how electron-electron interactions can lead to novel phenomena in double quantum wire systems. Explicitly, we find that double wires with time reversal symmetry and strong electron-electron interactions can exhibit fractional conductances and cross-conductances in their normal state. They also allow to pump the fraction of a spin in their superconducting state. These effects are an extension of fractional helical Luttinger liquid physics, and can be understood as the one-dimensional cousins of bilayer fractional quantum Hall effects.
