Interplay of spin and charge order in the electron-doped cuprates
David Riegler, Jannis Seufert, Eduardo H. da Silva Neto +3
We study magnetic and charge order in the electron-doped high- cuprates based on the one-band Hubbard model with onsite () and nearest-neighbor interactions. To inves…
Chiral Y-junction of Luttinger liquid wires at strong coupling: fermionic representation
D. N. Aristov, P. Wölfle
We calculate the conductances of a three-terminal junction set-up of spinless Luttinger liquid wires threaded by a magnetic flux, allowing for different interaction strength g_3 !=…
Two-band superconductivity in doped SrTiO films and interfaces
R. M. Fernandes, J. T. Haraldsen, P. Wölfle +1
We investigate the possibility of multi-band superconductivity in SrTiO films and interfaces using a two-dimensional two-band model. In the undoped compound, one of the bands…
Anderson impurity model at finite Coulomb interaction U: generalized Non-crossing Approximation
K. Haule, S. Kirchner, J. Kroha +1
We present an extension of the non-crossing approximation (NCA), which is widely used to calculate properties of Anderson impurity models in the limit of infinite Coulomb repulsion…
Diagrammatic theory of the Anderson impurity model with finite Coulomb interaction
K. Haule, S. Kirchner, J. Kroha +1
We have developed a self-consistent conserving pseudo particle approximation for the Anderson impurity model with finite Coulomb interaction, derivable from a Luttinger Ward functi…
Current noise in a irradiated point contact
Y. Levinson, P. Woelfle
We propose a new approach to calculate current and current correlations in a ballistic quantum point contact interacting with a classical field. The approach is based on the concep…
