Near-field imaginging of THz-metamaterials with Rydberg atoms

Descrizione

Near-field imaginging of THz-metamaterials with Rydberg atoms Sintesi in italiano (traduzione automatica): L'organizzazione internazionale cerca un ingegnere di ricerca per sviluppare una nuova piattaforma di sensing quantistico basata su atomi di Rydberg, focalizzata sull'imaging del campo elettromagnetico di metamateriali terahertz (THz). La posizione è presso il Laboratoire de Physique des Lasers e prevede la progettazione, fabbricazione e caratterizzazione di celle di vapore innovative integrate con metamateriali. Il candidato ideale avrà competenze in spettroscopia THz, sorgenti laser e spettroscopia atomica, oltre a una solida conoscenza delle interazioni luce-materia e della fisica atomica. È richiesta una laurea in fisica o ingegneria fisica. Il progetto è parte dell'iniziativa ANR PRC TERRA e mira a sviluppare una nuova forma di microscopia quantistica a campo vicino. Postoc The scientific objective of this position is to develop a new quantum sensing platform based on Rydberg atoms for probing the near field of terahertz (THz) metamaterials and imaging electromagnetic fields in the vicinity of subwavelength resonators. As a first step toward this long-term goal, the project aims to integrate THz metamaterials into atomic vapor cells and interface them with cesium atoms excited to Rydberg states by external laser excitation. This approach will enable the development of an original photonic platform combining atomic systems with metamaterials. In a second stage, the resonators will be excited by an external THz source to generate localized electromagnetic near fields. These fields will then be mapped with subwavelength spatial resolution, beyond the diffraction limit, using Rydberg atoms as quantum sensors. This approach will pave the way for a new form of quantum near-field microscopy, in which atomic probes replace the macroscopic tips employed in conventional scanning probe techniques. This research program constitutes one of the major objectives of the ANR PRC TERRA project. We are therefore seeking a research engineer who will play a central role in the design, fabrication, and characterization of this new generation of vapor cells incorporating metamaterials, as well as in the implementation of the first Rydberg spectroscopy and quantum THz near-field imaging experiments.Laboratory: Laboratoire de Physique des Lasers Field of research:Experimental quantum physics Skills : THz spectroscopy and sources, lasers, and atomic spectroscopy Knowledge : Light–matter interactions and atomic physics Annuncio in inglese.
