Multipolar edge states in the breathing kagome model
Judit Romhányi
Excitations of ordered insulating magnets gain renewed interest due to their potential topological properties and the natural realization of magnetic analogues of the celebrated to…
Magnetoelectric memory function with optical readout
Vilmos Kocsis, Karlo Penc, Toomas Rõõm +8
The ultimate goal of multiferroic research is the development of new-generation non-volatile memory devices, the so-called magnetoelectric (ME) memories, where magnetic bits are co…
Spin-Orbit Dimers and Non-Collinear Phases in Cubic Double Perovskites
Judit Romhányi, Leon Balents, George Jackeli
We formulate and study a spin-orbital model for a family of cubic double perovskites with ions occupying a frustrated fcc sublattice. A variational approach and a complimenta…
Orbital reconstruction in nonpolar tetravalent transition-metal oxide layers
Nikolay A. Bogdanov, Vamshi M. Katukuri, Judit Romhányi +5
A promising route to tailoring the electronic properties of quantum materials and devices rests on the idea of orbital engineering in multilayered oxide heterostructures. Here we s…
