Low-energy properties of fractional helical Luttinger liquids — •Tobias Meng¹, Lars Fritz², Dirk Schuricht³, and Daniel Loss¹ — ¹Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland — ²Institut für Theoretische Physik, Universität zu Köln, Zülpicher Straße 77, 50937 Köln, Germany — ³Institut für Theorie der Statistischen Physik, RWTH Aachen University and JARA - Fundamentals of Future Information Technology, 52056 Aachen, Germany

We discuss how fractional helical Luttinger liquids, a one-dimensional state related to the fractional quantum Hall effect, can emerge as a consequence of an intricate mixing of charge and spin degrees of freedom in a quantum wire. We discuss their unusual low energy physics with an emphasis on their fractional conductance, the optical conductivity and density of states.
