Asymmetric power dissipation in electronic transport through a quantum point contact
Carmen Blaas-Anselmi, Félix Helluin, Rodolfo A. Jalabert +2
We investigate the power dissipated by an electronic current flowing through a quantum point contact in a two-dimensional electron gas. Based on the Landauer-Büttiker approach to q…
Spontaneous orbital magnetization of mesoscopic dipole dimers
Gaëtan J. Percebois, Dietmar Weinmann, Rodolfo A. Jalabert +1
Ensembles of gold nanoparticles present a magnetic behavior which is at odds with the weakly diamagnetic response of bulk gold. In particular, an unusual ferromagnetic order has be…
Quantum theory of plasmon polaritons in chains of metallic nanoparticles: From near- to far-field coupling regime
Thomas F. Allard, Guillaume Weick
We develop a quantum theory of plasmon polaritons in chains of metallic nanoparticles, describing both near- and far-field interparticle distances, by including plasmon-photon Umkl…
Magnetic response of metallic nanoparticles: Geometric and weakly relativistic effects
Mauricio Gómez Viloria, Guillaume Weick, Dietmar Weinmann +1
While the large paramagnetic response measured in certain ensembles of metallic nanoparticles has been assigned to orbital effects of conduction electrons, the spin-orbit coupling…
