Orbital embedding and topology of one-dimensional two-band insulators
J. -N. Fuchs, F. Piéchon
The topological invariants of band insulators are usually assumed to depend only on the connectivity between orbitals and not on their intra-cell position (orbital embedding), whic…
Landau levels, response functions and magnetic oscillations from a generalized Onsager relation
J. N. Fuchs, F. Piéchon, G. Montambaux
A generalized semiclassical quantization condition for cyclotron orbits was recently proposed by Gao and Niu \cite{Gao}, that goes beyond the Onsager relation \cite{Onsager}. In ad…
Competition between Spin Echo and Spin Self-Rephasing in a Trapped Atom Interferometer
Cyrille Solaro, Alexis Bonnin, Frédéric Combes +5
We perform Ramsey interferometry on an ultracold 87Rb ensemble confined in an optical dipoletrap. We use a π-pulse set at the middle of the interferometer to restore the coherence…
Orbital magnetism of coupled bands models
A. Raoux, F. Piéchon, J. N. Fuchs +1
We develop a gauge-independent perturbation theory for the grand potential of itinerant electrons in two-dimensional tight-binding models in the presence of a perpendicular magneti…
