Many-particle effects in adsorbed magnetic atoms with easy-axis anisotropy: the case of Fe on CuN/Cu(100) surface

Rok Zitko, Thomas Pruschke

We study the effects of the exchange interaction between an adsorbed magnetic atom with easy-axis magnetic anisotropy and the conduction-band electrons from the substrate. We model…

LDA+DMFT study for

M. B. Zoelfl, Th. Pruschke, J. Keller +3

The dynamical mean-field theory together with the non-crossing approximation is used to set up a novel scheme to study the electronic structure of strongly correlated electron syst…

A Non-Crossing Approximation for the Study of Intersite Correlations

Th. Maier, M. Jarrell, Th. Pruschke +1

We develop a Non-Crossing Approximation (NCA) for the effective cluster problem of the recently developed Dynamical Cluster Approximation (DCA). The DCA technique includes short-ra…

Effects of spin fluctuations in the t-J model

T. Obermeier, T. Pruschke, J. Keller

Recent experiments on the Fermi surface and the electronic structure of the cuprate-supercondutors showed the importance of short range antiferromagnetic correlations for the physi…

Functional Integral Approach to the Single Impurity Anderson Model

R. Bulla, J. Keller, T. Pruschke

Recently, a functional integral representation was proposed by Weller (Weller, W.: phys.~stat.~sol.~(b) {\bf 162}, 251 (1990)), in which the fermionic fields strictly satisfy the c…
