Theory of the strongly disordered Weyl semimetal
Alexander Altland, Dmitry Bagrets
In disordered Weyl semimetals, mechanisms of topological origin lead to novel mechanisms of transport, which manifest themselves in unconventional types of electromagnetic response…
Towards realistic implementations of a Majorana surface code
L. A. Landau, S. Plugge, E. Sela +3
Surface codes have emerged as promising candidates for quantum information processing. Building on the previous idea to realize the physical qubits of such systems in terms of Majo…
U(1) and SU(2) quantum dissipative systems: The Caldeira-Leggett vs. the Amegaokar-Eckern-Schön approaches
Alexander Shnirman, Arijit Saha, Igor S. Burmistrov +3
There are two paradigmatic frameworks for treating quantum systems coupled to a dissipative environment: the Caldeira-Leggett and the Ambegaokar-Eckern-Schön approaches. Here we re…
Intermediate fixed point in a Luttinger liquid with elastic and dissipative backscattering
Alexander Altland, Yuval Gefen, Bernd Rosenow
In a recent work [Phys. Rev. Lett. {\bf 108}, 136401 (2012)] we have addressed the problem of a Luttinger liquid with a scatterer that allows for both coherent and incoherent scatt…
Effective field theory of the disordered Weyl semimetal
Alexander Altland, Dmitry Bagrets
In disordered Weyl semimetals, mechanisms of topological origin lead to the protection against Anderson localization, and at the same time to different types of transverse electrom…
