Field dependent mass enhancement in Pr_{1-x}La_xOs_4Sb_12 from aspherical Coulomb scattering
G. Zwicknagl, P. Thalmeier, P. Fulde
The scattering of conduction electrons by crystalline electric field (CEF) excitations may enhance their effective quasiparticle mass similar to scattering from phonons. A wellknow…
Theory of Spin Exciton in the Kondo Semiconductor
Alireza Akbari, Peter Thalmeier, Peter Fulde
The Kondo semiconductor exhibits a spin and charge gap of approximately 15 meV. Close to the gap energy narrow dispersive collective excitations were identified by prev…
Correlated electrons in Fe-As compounds: a quantum chemical perspective
L. Hozoi, P. Fulde
State-of-the-art quantum chemical methods are applied to the study of the multiorbital correlated electronic structure of a Fe-As compound, the recently discovered LiFeAs. Our calc…
Strongly correlated electrons on frustrated lattices
Peter Fulde, Frank Pollmann, Erich Runge
We give an overview of recent work on charge degrees of freedom of strongly correlated electrons on geometrically frustrated lattices. Special attention is paid to the checkerboard…
Spin-state transition and spin-polaron physics in cobalt oxide perovskites: ab initio approach based on quantum chemical methods
L. Hozoi, U. Birkenheuer, H. Stoll +1
A fully ab initio scheme based on quantum chemical wavefunction methods is used to investigate the correlated multiorbital electronic structure of a 3d-metal compound, LaCoO3. The…
Strings in strongly correlated electron systems
P. Fulde, F. Pollmann
It is shown that strongly correlated electrons on frustrated lattices like pyrochlore, checkerboard or kagome lattice can lead to the appearance of closed and open strings. They ar…
