Ergodicity breaking in frustrated disordered systems: Replicas in mean-field spin-glass models
V. Janis, A. Kauch, A. Klic
We discuss ergodicity breaking in frustrated disordered systems with no apparent broken symmetry of the Hamiltonian and present a way how to amend it in the low-temperature phase.…
Thermodynamic origin of order parameters in mean-field models of spin glasses
V. Janis, L. Zdeborova
We analyze thermodynamic behavior of general -component mean-field spin glass models in order to identify origin of the hierarchical structure of the order parameters from the r…
Parquet approach to nonlocal vertex functions and electrical conductivity of disordered electrons
V. Janis
A diagrammatic technique for two-particle vertex functions is used to describe systematically the influence of spatial quantum coherence and backscattering effects on transport pro…
Conductivity of disordered electrons: Mean-field approximation containing vertex corrections
V. Janis, D. Vollhardt
The electrical {\em dc}-conductivity of disordered, non-interacting electrons is calculated in the asymptotic limit of high lattice dimensions . To go beyond the lowes…
Fluctuation-driven insulator-to-metal transition in an external magnetic field
V. Janis, G. Czycholl
We consider a model for a metal-insulator transition of correlated electrons in an external magnetic field. We find a broad region in interaction and magnetic field where metallic…
Stability of self-consistent solutions for the Hubbard model at intermediate and strong coupling
V. Janis
We present a general framework how to investigate stability of solutions within a single self-consistent renormalization scheme being a parquet-type extension of the Baym-Kadanoff…
