Seminarios del Departamento de Física de la Materia Condensada 2022: “Quantum trapping based on the Casimir force” .- Viernes 11 de marzo
El viernes 11 de marzo a las 12:30 h tendrá lugar la conferencia de este ciclo que impartirá Sol Carretero (Universidad Autónoma de Madrid). Se titula "Quantum trapping based on the Casimir force ".
La charla se realizará en la Sala de Grados del edificio A (Físicas) de la Facultad de Ciencias. La sesión será grabada y colgada posteriormente en el canal de Youtube del departamento para que pueda ser visualizada por quienes no puedan asistir.
Resumen
The Casimir-Lifshitz force originates from the quantum vacuum fluctuations of the electromagnetic field. This force is especially intense between interacting objects at nanoscale distances, and it can be attractive or repulsive depending on the optical properties of the materials involved (amongst other parameters). This fundamental phenomenon is at the heart of the malfunctioning of nano- and micro-electromechanical devices (NEMS and MEMS) that integrate many of the gadgets we use in our daily lives. Absolute control over these forces would make it possible to suppress adhesion and friction in these NEMs and MEMs.
During this talk, I will show the possibility of controlling the Casimir-Lifshitz force by tuning the optical properties of the interacting objects. Specifically, I will present diverse examples of quantum levitation of self-standing thin films comprising multilayer structures or films with spatial inhomogeneities, based on the Casimir-Lifshitz force.
