The self-consistent quantum-electrostatic problem in strongly non-linear regime
P. Armagnat, A. Lacerda-Santos, B. Rossignol +2
The self-consistent quantum-electrostatic (also known as Poisson-Schrödinger) problem is notoriously difficult in situations where the density of states varies rapidly with energy.…
Reconciling edge states with compressible stripes in a ballistic mesoscopic conductor
Pacome Armagnat, Xavier Waintal
The well-known Landauer-Buttiker (LB) picture used to explain the quantum Hall effect uses the concept of (chiral) edge states that carry the current. In their seminal 1992 article…
Toward flying qubit spectroscopy
Benoit Rossignol, Thomas Kloss, Pacome Armagnat +1
While the coherent control of two level quantum systems ---qubits--- is now standard, their continuum electronic equivalents ---flying qubits--- are much less developed. A first st…
Exact density profiles and symmetry classification for strongly interacting multi-component Fermi gases in tight waveguides
Jean Decamp, Pacome Armagnat, Bess Fang +3
We consider a mixture of one-dimensional strongly interacting Fermi gases up to six components, subjected to a longitudinal harmonic confinement. In the limit of infinitely strong…
