Spin susceptibility in interacting two-dimensional semiconductors and bilayer systems at first order: Kohn anomalies and spin density wave ordering
Joel Hutchinson, Dmitry Miserev, Jelena Klinovaja +1
This work is an analytic theoretical study of a 2D semiconductor with a Fermi surface that is split by the Zeeman coupling of electron spins to an external magnetic field in the pr…
Magnetoelectric Cavity Magnonics in Skyrmion Crystals
Tomoki Hirosawa, Alexander Mook, Jelena Klinovaja +1
We present a theory of magnetoelectric magnon-photon coupling in cavities hosting noncentrosymmetric magnets. Analogously to nonreciprocal phenomena in multiferroics, the magnetoel…
Instability of the ferromagnetic quantum critical point in strongly interacting 2D and 3D electron gases with arbitrary spin-orbit splitting
Dmitry Miserev, Daniel Loss, Jelena Klinovaja
In this work we revisit itinerant ferromagnetism in 2D and 3D electron gases with arbitrary spin-orbit splitting and strong electron-electron interaction. We identify the resonant…

Flavio Ronetti, Daniel Loss, Jelena Klinovaja
We investigate theoretically the spiral staircase Heisenberg spin- ladder in the presence of antiferromagnetic long-range spin interactions and a uniform magnetic field. As a…
Laser-controlled real- and reciprocal-space topology in multiferroic insulators
Tomoki Hirosawa, Jelena Klinovaja, Daniel Loss +1
Magnetic materials in which it is possible to control the topology of their magnetic order in real space or the topology of their magnetic excitations in reciprocal space are highl…
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…
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…
Fermi Surface Resonance and Quantum Criticality in Strongly Interacting Fermi Gases
Dmitry Miserev, Jelena Klinovaja, Daniel Loss
Fermions in the Fermi gas obey the Pauli exclusion principle restricting any two fermions from filling the same quantum state. Strong interaction between fermions can completely ch…
Magnonic Quadrupole Topological Insulator in Antiskyrmion Crystals
Tomoki Hirosawa, Sebastian A. Diaz, Jelena Klinovaja +1
When the crystalline symmetries that protect a higher-order topological phase are not preserved at the boundaries of the sample, gapless hinge modes or in-gap corner states cannot…
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…
Chiral Magnonic Edge States in Ferromagnetic Skyrmion Crystals Controlled by Magnetic Fields
Sebastian A. Diaz, Tomoki Hirosawa, Jelena Klinovaja +1
Achieving control over magnon spin currents in insulating magnets - where dissipation due to Joule heating is highly suppressed - is an active area of research that could lead to e…

Dmitry Miserev, Jelena Klinovaja, Daniel Loss
We analyze magnetic phases of monolayers of transition metal dichalcogenides that are two-valley materials with electron-electron interactions. The exchange inter-valley scattering…

Franziska Maier, Tobias Meng, Daniel Loss
We consider holes confined to Ge/Si core/shell nanowires subject to strong Rashba spin-orbit interaction and screened Coulomb interaction. Such wires can, for instance, serve as ho…
