Geometric orbital susceptibility: quantum metric without Berry curvature
Frédéric Piéchon, Arnaud Raoux, Jean-Noël Fuchs +1
The orbital magnetic susceptibility of an electron gas in a periodic potential depends not only on the zero field energy spectrum but also on the geometric structure of cell-period…
Tunable orbital susceptibility in - tight-binding models
F. Piéchon, J-N. Fuchs, A. Raoux +1
We study the importance of interband effects on the orbital susceptibility of three bands - tight-binding models. The particularity of these models is that the coupl…
Ab-Initio Theory of Moiré Superlattice Bands in Layered Two-Dimensional Materials
Jeil Jung, Arnaud Raoux, Zhenhua Qiao +1
When atomically thin two-dimensional (2D) materials are layered they often form incommensurate non-crystalline structures that exhibit long-period moir{\' e} patterns when examined…
From dia- to paramagnetic orbital susceptibility of Dirac cones
A. Raoux, M. Morigi, J. N. Fuchs +2
We study the orbital susceptibility of coupled energy bands with a pair of Dirac points, as in graphene. We show that different systems having the same zero-field energy spectrum e…
Spin Drag in Ultracold Fermi Mixtures with Repulsive Interactions
R. A. Duine, Marco Polini, Arnaud Raoux +2
We calculate the spin-drag relaxation rate for a two-component ultracold atomic Fermi gas with positive scattering length between the two spin components. In one dimension we find…
Velocity-modulation control of electron-wave propagation in graphene
Arnaud Raoux, Marco Polini, Reza Asgari +3
Wave propagation control by spatial modulation of velocity has a long history in optics and acoustics. We address velocity-modulation control of electron wave propagation in graphe…
