Production of non-local quartets and phase-sensitive entanglement in a superconducting beam splitter
Axel Freyn, Benoit Douçot, Denis Feinberg +1
Three BCS superconductors S_a, S_b, and S and two short normal regions N_a and N_b in a three-terminal S_aN_aSN_bS_b set-up provide a source of non-local quartets spatially separat…
Voltage-Current curves for small Josephson junction arrays
Benoit Doucot, Lev B. Ioffe
We compute the current voltage characteristic of a chain of identical Josephson circuits characterized by a large ratio of Josephson to charging energy that are envisioned as the i…
Quasiparticle spectrum of the cuprate BiSrCaCuO: Possible connection to the phase diagram
W. Sacks, T. Cren, D. Roditchev +1
We previously introduced [T. Cren et al., Europhys. Lett. 52, 203 (2000)] an energy-dependant gap function, , that fits the unusual shape of the quasiparticle (QP) spectrum f…
Non-Abelian Chern-Simons models with discrete gauge groups on a lattice
B. Doucot, L. B. Ioffe
We construct the local Hamiltonian description of the Chern-Simons theory with discrete non-Abelian gauge group on a lattice. We show that the theory is fully determined by the pha…
Structure of the superconducting state in a fully frustrated wire network with dice lattice geometry
S. E. Korshunov, B. Doucot
The superconducting state in a fully frustrated wire network with the dice lattice geometry is investigated in the vicinity of the transition temperature. Using Abrikosov's variati…
Protected Qubits and Chern Simons theories in Josephson Junction Arrays
B. Doucot, M. V. Feigel'man, L. B. Ioffe +1
We present general symmetry arguments that show the appearance of doubly denerate states protected from external perturbations in a wide class of Hamiltonians. We construct the sim…
