Quantum Spins and Quasiperiodicity: a real space renormalization group approach
A. Jagannathan
We study the antiferromagnetic spin-1/2 Heisenberg model on a two-dimensional bipartite quasiperiodic structure, the octagonal tiling -- the aperiodic equivalent of the square latt…
Weak localization in multiterminal networks of diffusive wires
Christophe Texier, Gilles Montambaux
We study the quantum transport through networks of diffusive wires connected to reservoirs in the Landauer-Büttiker formalism. The elements of the conductance matrix are computed b…
Effect of interactions on the noise of chiral Luttinger liquid systems
B. Trauzettel, P. Roche, D. C. Glattli +1
We analyze the current noise, generated at a quantum point contact in fractional quantum Hall edge state devices, using the chiral Luttinger liquid model with an impurity and the a…
A one-channel conductor in an ohmic environment: mapping to a TLL and full counting statistics
Ines Safi, Hubert Saleur
It is shown that a one-channel mesoscopic conductor in an ohmic environment can be mapped to the problem of a backscattering impurity in a Tomonaga-Luttinger liquid (TLL). This all…
Identifying the Background Signal in ARPES of High Temperature Superconductors
A. Kaminski, S. Rosenkranz, H. M. Fretwell +9
One of the interesting features of the photoemission spectra of the high temperature cuprate superconductors is the presence of a large signal (referred to as the "background'') in…
Oscillatory non-linear conductance of an interacting quantum wire with an impurity
Fabrizio Dolcini, Hermann Grabert, Ines Safi +1
The nonlinear conductance of a one-dimensional quantum wire adiabatically coupled to Fermi Liquid electron reservoirs is determined in presence of an impurity. We show that electro…
