Bosonic continuum theory of one-dimensional lattice anyons

M. Bonkhoff, K. Jägering, S. Eggert +3

Anyons with arbitrary exchange phases exist on 1D lattices in ultracold gases. Yet, known continuum theories in 1D do not match. We derive the continuum limit of 1D lattice anyons…

Topological superconductivity induced by a triple-Q magnetic structure

Jasmin Bedow, Eric Mascot, Thore Posske +4

We demonstrate that the recently discovered triple-Q (3Q) magnetic structure, when embedded in a magnet-superconductor hybrid (MSH) system, gives rise to the emergence of topologic…

Controlling in-gap end states by linking nonmagnetic atoms and artificially-constructed spin chains on superconductors

Lucas Schneider, Sascha Brinker, Manuel Steinbrecher +6

Chains of magnetic atoms with either strong spin-orbit coupling or spiral magnetic order which are proximity-coupled to superconducting substrates can host topologically non-trivia…

Vortex Majorana braiding in a finite time

Thore Posske, Ching-Kai Chiu, Michael Thorwart

Abrikosov vortices in Fe-based superconductors are a promising platform for hosting Majorana zero modes. Their adiabatic exchange is a key ingredient for Majorana-based quantum com…

Winding up quantum spin helices: How avoided level crossings exile classical topological protection

Thore Posske, Michael Thorwart

A magnetic helix can be wound into a classical Heisenberg chain by fixing one end while rotating the other one. We show that in quantum Heisenberg chains \new{of finite length}, th…

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…
