Quantum Magnetic Skyrmion Operator

Andreas Haller, Sebastián A. Díaz, Wolfgang Belzig +1

We propose a variational wave function to represent quantum skyrmions as bosonic operators. The operator faithfully reproduces two fundamental features of quantum skyrmions: their…

Manipulating Vortices with Domain Walls in Superconductor-Ferromagnet Heterostructures

Sebastián A. Díaz, Jonas Nothhelfer, Kjetil M. D. Hals +1

Vortices are point-like topological defects in superconductors whose motion dictates superconducting properties and controls device performance. In superconductor-ferromagnet heter…

Steering Majorana braiding via skyrmion-vortex pairs: a scalable platform

Jonas Nothhelfer, Sebastián A. Díaz, Stephan Kessler +4

Majorana zero modes are quasiparticles that hold promise as building blocks for topological quantum computing. However, the litmus test for their detection, the observation of exot…

Majorana Bound States Induced by Antiferromagnetic Skyrmion Textures

Sebastián A. Díaz, Jelena Klinovaja, Daniel Loss +1

Majorana bound states are zero-energy states predicted to emerge in topological superconductors and intense efforts seeking a definitive proof of their observation are still ongoin…

Chiral Hinge Magnons in Second-Order Topological Magnon Insulators

Alexander Mook, Sebastián A. Díaz, Jelena Klinovaja +1

When interacting spins in condensed matter order ferromagnetically, their ground state wave function is topologically trivial. Nonetheless, in two dimensions, the ferromagnetic sta…
