Magnons in multiorbital Hubbard models, from Lieb to kagome
Teng-Fei Ying, Hugo U. R. Strand, Benjamin T. Zhou +1
We investigate the magnetic orders and excitations in a half-filled Hubbard model that continuously interpolates between the Lieb and kagome lattices. Using self-consistent Hartree…
Doping-dependent charge- and spin-density wave orderings in a monolayer of Pb adatoms on Si(111)
Matteo Vandelli, Anna Galler, Angel Rubio +3
In this work we computed the phase diagram as a function of temperature and doping for a system of lead adatoms allocated periodically on a silicon (111) surface. This Si(111):Pb m…
Observation of a new light-induced skyrmion phase in the Mott insulator Cu2OSeO3
Alexey A. Sapozhnik, Benoit Truc, Phoebe Tengdin +10
We report the discovery of a novel skyrmion phase in the multiferroic insulator Cu2OSeO3 for magnetic fields below the equilibrium skyrmion pocket. This phase can be accessed by ex…
The dimer system KNi(MoO): a candidate for magnon Bose-Einstein condensation
B. Lenz, B. Koteswararao, S. Biermann +3
Dimerized quantum magnets provide a unique possibility to investigate Bose-Einstein condensation of magnetic excitations in crystalline systems at low temperature. Here, we model t…
Renormalization of effective interactions in a negative charge-transfer insulator
Priyanka Seth, Oleg E. Peil, Leonid Pourovskii +6
We compute from first principles the effective interaction parameters appropriate for a low-energy description of the rare-earth nickelate LuNiO involving the partially occup…
