Resonant inelastic X-ray scattering in a Mott insulator
Nandan Pakhira, J. K. Freericks, A. M. Shvaika
We calculate the resonant inelastic X-ray scattering (RIXS) response in a Mott insulator which is described by the Falicov-Kimball model. The model can be solved exactly within the…
Localized states on triangular traps and low-temperature properties of the antiferromagnetic Heisenberg and repulsive Hubbard models
Mykola Maksymenko, Oleg Derzhko, Johannes Richter
We consider the antiferromagnetic Heisenberg and the repulsive Hubbard model on two -site one-dimensional lattices, which support dispersionless one-particle states correspondin…
Magnetism and superconductivity at LAO/STO-interfaces: the role of Ti 3d interface electrons
N. Pavlenko, T. Kopp, E. Y. Tsymbal +2
Ferromagnetism and superconductivity are in most cases adverse. However, recent experiments reveal that they coexist at interfaces of LaAlO3 and SrTiO3. We analyze the magnetic sta…
Quantum Heisenberg antiferromagnet on low-dimensional frustrated lattices
Oleg Derzhko, Taras Krokhmalskii, Johannes Richter
Using a lattice-gas description of the low-energy degrees of freedom of the quantum Heisenberg antiferromagnet on the frustrated two-leg ladder and bilayer lattices we examine the…
