Charge conservation protected topological phases
Jan Carl Budich
We discuss the relation between particle number conservation and topological phases. In four spatial dimensions, we find that systems belonging to different topological phases in t…
Majorana bound states and non-local spin correlations in a quantum wire on an unconventional superconductor
Sho Nakosai, Jan Carl Budich, Yukio Tanaka +2
We study theoretically the proximity effect of a one-dimensional metallic quantum wire (in the absence of spin-orbit interaction) lying on top of an unconventional superconductor.…
From the adiabatic theorem of quantum mechanics to topological states of matter
Jan Carl Budich, Björn Trauzettel
Owing to the enormous interest the rapidly growing field of topological states of matter (TSM) has attracted in recent years, the main focus of this review is on the theoretical fo…
Exact results for the Kondo screening cloud of two helical liquids
Thore Posske, Chao-Xing Liu, Jan Carl Budich +1
We analyze the screening of a magnetic quantum dot with spin 1/2 coupled to two helical liquids. Interestingly, we find two qualitatively different sets of Toulouse points, i.e., n…
