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…
