Mesoscopic Full Counting Statistics and Exclusion models
Philippe-E. Roche, Bernard Derrida, Benoit Doucot
We calculate the distribution of current fluctuations in two simple exclusion models. Although these models are classical, we recover even for small systems such as a simple or a d…
Weakly interacting electrons and the renormalization group
B. Binz, D. Baeriswyl, B. Doucot
We present a general method to study weak-coupling instabilities of a large class of interacting electron models in a controlled and unbiased way. Quite generally, the electron gas…
Current fluctuations in the one dimensional Symmetric Exclusion Process with open boundaries
B Derrida, B Doucot, P. -E. Roche
We calculate the first four cumulants of the integrated current of the one dimensional symmetric simple exclusion process of sites with open boundary conditions. For large syst…
Fluctuations and vortex pattern ordering in fully frustrated XY model with honeycomb lattice
S. E. Korshunov, B. Doucot
The accidental degeneracy of various ground states in a fully frustrated XY model with a honeycomb lattice is shown to survive even when the free energy of the harmonic fluctuation…
Discrete non-Abelian gauge theories in two-dimensional lattices and their realizations in Josephson-junction arrays
B. Doucot, L. B. Ioffe, J. Vidal
We discuss real-space lattice models equivalent to gauge theories with a discrete non-Abelian gauge group. We construct the Hamiltonian formalism which is appropriate for their sol…
