Photon mediated transport of energy, linear momentum, and angular momentum in fullerene and graphene systems beyond local equilibrium Auteur(s): Wang Jian-sheng, Antezza M. (Article) Publié: Physical Review B, vol. 109 p.125105 (2024) DOI: 10.1103/PhysRevB.109.125105 Résumé: Based on a tight-binding model for the electron system, we investigate the transfer of energy, momentum, and angular momentum mediated by electromagnetic fields among buckminsterfullerene ( C 60 ) and graphene nanostrips. Our nonequilibrium Green's function approach enables calculations away from local thermal equilibrium where the fluctuation-dissipation theorem breaks down. For example, the forces between C 60 and current-carrying nanostrips are predicted. It is found that the presence of current enhances the van der Waals attractive forces. For two current-carrying graphene strips rotated at some angle, the fluctuational force and torque are much stronger at the nanoscale compared to that of the static Biot-Savart law. |
