Spin-Hall devices: spin relaxation spatially separates current injection from Joule dissipation
Yanbo Qiao, Sariah Al Saati, Jean-Eric Wegrowe
The stationary state of a spin Hall bar connected to an external load circuit is investigated through a variational approach based on the principle of minimum power dissipation gen…

Theory of local orbital magnetization: local Berry curvature
Sariah Al Saati, Karyn Le Hur, Frédéric Piéchon
We develop a thermodynamic theory of local orbital magnetization based on a perturbative expansion of the magnetic-field-dependent local density of states. Applicable to periodic c…

Quantum Hall and Light Responses in a 2D Topological Semimetal
Karyn Le Hur, Sariah Al Saati
We have recently identified a protected topological semimetal in graphene which presents a zero-energy edge mode robust to disorder and interactions. Here, we address the character…
