El ciclo de seminarios De Madrid al Cosmos busca la difusión de la investigación en cosmología teórica y temas relacionados. Los seminarios del ciclo pretenden ser accesibles a un público no especializado, pero con conocimientos de física fundamental.

El ciclo está organizado conjuntamente por el Grupo de Teorías Efectivas en Física Moderna de la Universidad Complutense de Madrid y el Grupo de Gravitación y Cosmología del Instituto de Estructura de la Materia (IEM-CSIC).

On the non-local surface plasmon contribution to the Casimir force

Ponente: Vincenzo Giannini
Filiación: IEM-CSIC
Resumen: The Casimir effect is a fundamental quantum-mechanical relativistic phenomenon which originates from the vacuum fluctuations of the electromagnetic field. It interconnects electrically neutral objects with or without permanent electric and/or magnetic moments. Using a quantum electrodynamical approach based on linear response theory we will show a detailed study of the Casimir force in graphene systems. Graphene is a two-dimensional crystal that has singular electronic, mechanical and optical properties. Being graphene a one atom thick structure makes particularly interesting to study Casimir forces between graphene sheets. The graphene sheets are considered as infinitesimal thin, local and isotropic conductive surfaces and furthermore, the influence of surface plasmons is explored. We will see how this fundamental effect depends on the graphene optical response and the gap. In this way, we are able to study the light-plasmon mediated interaction between graphene sheets. These results are particularly relevant for graphene nanotechnology applications.
