Localization in ruthenates: magnetic and electronic properties of Ca(2-x)Sr(x)RuO(4)
V. I. Anisimov, I. A. Nekrasov, D. E. Kondakov +2
The electronic structures of the metallic and insulating phases of Ca(2-x)Sr(x)RuO(4) (0<= x <= 2) are calculated using LDA, LDA+U and Dynamical Mean-Field Approximation methods. F…
Edge Singularity for the Optically Induced Kondo Effect in a Quantum Dot
T. Fujii, A. Furusaki, N. Kawakami +1
We analyze the optically induced Kondo effect in the absorption spectrum for a quantum dot with an even number of electrons, for which the Kondo effect does not occur in the ground…
Chiral feedback for p-wave superconductors
J. Goryo, M. Sigrist
In a quasi-two-dimensional -wave superconductor there find six Cooper pairing states which are degenerate within the weak-coupling approach. We show that this degeneracy can b…
Order by disorder from non-magnetic impurities in a two-dimensional quantum spin liquid
S. Wessel, B. Normand, M. Sigrist +1
We consider doping of non-magnetic impurities in the spin-1/2, 1/5-depleted square lattice. This structure, whose undoped phase diagram offers both magnetically ordered and spin-li…
The influence of chiral surface states on the London penetration depth in SrRuO
Takao Morinari, Manfred Sigrist
The London penetration depth for the unconventional superconductor SrRuO is analyzed assuming an order parameter which breaks time reversal symmetry and parity simultaneous…
