Kramers' degeneracy for open systems in thermal equilibrium
Simon Lieu, Max McGinley, Oles Shtanko +2
Kramers' degeneracy theorem underpins many interesting effects in quantum systems with time-reversal symmetry. We show that the generator of dynamics for Markovian open fermionic s…
Elastic backscattering of quantum spin Hall edge modes from Coulomb interactions with non-magnetic impurities
Max McGinley, Nigel R. Cooper
We demonstrate that electrostatic interactions between helical electrons at the edge of a quantum spin Hall insulator and a dynamical impurity can induce quasi-elastic backscatteri…
Tenfold Way for Quadratic Lindbladians
Simon Lieu, Max McGinley, Nigel R. Cooper
We uncover a topological classification applicable to open fermionic systems governed by a general class of Lindblad master equations. These `quadratic Lindbladians' can be capture…
Topology of one dimensional quantum systems out of equilibrium
Max McGinley, Nigel R. Cooper
We study the topological properties of one dimensional systems undergoing unitary time evolution. We show that symmetries possessed both by the initial wavefunction and by the Hami…
Robustness of Majorana edge modes and topological order -- exact results for the symmetric interacting Kitaev chain with disorder
Max McGinley, Johannes Knolle, Andreas Nunnenkamp
We investigate the robustness of Majorana edge modes under disorder and interactions. We exploit a recently found mapping of the interacting Kitaev chain in the symmetric region ($…
