Critical behavior and universality in Levy spin glasses
Juan Carlos Andresen, Katharina Janzen, Helmut G. Katzgraber
Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share…

Replica theory for Levy spin glasses
K. Janzen, A. K. Hartmann, A. Engel
Infinite-range spin-glass models with Levy-distributed interactions show a spin-glass transition with similarities to both the Sherrington-Kirkpatrick model and to disordered spin…

Influence of the contacts on the conductance of interacting quantum wires
K. Janzen, V. Meden, K. Schoenhammer
We investigate how the conductance G through a clean interacting quantum wire is affected by the presence of contacts and noninteracting leads. The contacts are defined by a vanish…
