Interaction-stabilized topological magnon insulator in ferromagnets
Alexander Mook, Kirill Plekhanov, Jelena Klinovaja +1
Condensed matter systems admit topological collective excitations above a trivial ground state, an example being Chern insulators formed by Dirac bosons with a gap at finite energi…
Quadrupole spin polarization as signature of second-order topological superconductors
Kirill Plekhanov, Niclas Müller, Yanick Volpez +4
We study theoretically second-order topological superconductors characterized by the presence of pairs of zero-energy Majorana corner states. We uncover a quadrupole spin polarizat…
Majorana bound states in topological insulators with hidden Dirac points
Ferdinand Schulz, Kirill Plekhanov, Daniel Loss +1
We address the issue whether it is possible to generate Majorana bound states at the magnetic-superconducting interface in two-dimensional topological insulators with hidden Dirac…
Magnetically-Confined Bound States in Rashba Systems
Flavio Ronetti, Kirill Plekhanov, Daniel Loss +1
A Rashba nanowire is subjected to a magnetic field that assumes opposite signs in two sections of the nanowire, and, thus, creates a magnetic domain wall. The direction of magnetic…
Hinge states in a system of coupled Rashba layers
Kirill Plekhanov, Flavio Ronetti, Daniel Loss +1
We consider a system of stacked tunnel-coupled two-dimensional electron- and hole-gas layers with Rashba spin-orbit interactions subjected to a staggered Zeeman field. The interpla…
Floquet Second-Order Topological Superconductor Driven via Ferromagnetic Resonance
Kirill Plekhanov, Manisha Thakurathi, Daniel Loss +1
We consider a Floquet triple-layer setup composed of a two-dimensional electron gas with spin-orbit interactions, proximity coupled to an s-wave superconductor and to a ferromagnet…
