Triplet superconducting pairing and density-wave instabilities in organic conductors
J. C. Nickel, R. Duprat, C. Bourbonnais +1
Using a renormalization group approach, we determine the phase diagram of an extended quasi-one-dimensional electron gas model that includes interchain hopping, nesting deviations…
Full counting statistics for the Kondo dot
A. Komnik, A. O. Gogolin
The generating function for the cumulants of charge current distribution is calculated for two generalised Majorana resonant level models: the Kondo dot at the Toulouse point and t…
Single particle spectrum of the flux phase in the FM Kondo Model
M. Daghofer, W. Koller, W. von der Linden +1
We investigate the 2D ferromagnetic Kondo lattice model for manganites with classical corespins at Hund's rule coupling J_H=6, with antiferromagnetic superexchange 0.03 < J' < 0.05…
First- and Second Order Phase Transitions in the Holstein-Hubbard Model
W. Koller, D. Meyer, Y. Ono +1
We investigate metal-insulator transitions in the Holstein-Hubbard model as a function of the on-site electron-electron interaction U and the electron-phonon coupling g. We use sev…
