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…
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…
Orbital Magnetic Moment of Magnons
Robin R. Neumann, Alexander Mook, Jürgen Henk +1
In experiments and applications usually the spin magnetic moment of magnons is considered. In this Paper we identify an additional degree of freedom of magnons: an \emph{orbital} m…
Compensated Quantum and Topological Hall Effects of Electrons in Polyatomic Stripe Lattices
Börge Göbel, Alexander Mook, Jürgen Henk +1
The quantum Hall effect is generally understood for free electron gases, in which topologically protected edge states between Landau levels (LLs) form conducting channels at the ed…
Quantum Damping of Skyrmion Crystal Eigenmodes due to Spontaneous Quasiparticle Decay
Alexander Mook, Jelena Klinovaja, Daniel Loss
The elementary excitations of skyrmion crystals experience both emergent magnetic fields and anharmonic interactions brought about by the topologically nontrivial noncollinear text…
