Low-energy properties of the Kondo lattice model
O. Bodensiek, R. Zitko, R. Peters +1
We study the zero-temperature properties of the Kondo lattice model within the dynamical mean-field theory. As impurity solver we use the numerical renormalization group. We presen…
Adaptive Lanczos-vector method for dynamic properties within the density-matrix renormalization group
P. E. Dargel, A. Honecker, R. Peters +2
Current widely-used approaches to calculate spectral functions using the density-matrix renormalization group in frequency space either necessarily include an artificial broadening…
Multi-step approach to microscopic models for frustrated quantum magnets - the case of the natural mineral azurite
Harald Jeschke, Ingo Opahle, Hem Kandpal +14
The natural mineral azurite Cu(CO)(OH) is a frustrated magnet displaying unusual and controversially discussed magnetic behavior. Motivated by the lack of a unified…
Orbital Order, Metal Insulator Transition, and Magnetoresistance-Effect in the two-orbital Hubbard model
Robert Peters, Norio Kawakami, Thomas Pruschke
We study the effects of temperature and magnetic field on a two-orbital Hubbard model within dynamical mean field theory. We focus on the quarter filled system, which is a special…
