Post-doctoral position available at the Laboratoire des Solides irradiés (one year)

Project :  The applicant will be working on the project  “Jasmin-T”( « Josephson plasmonics in high-Tc superconducting cuprates ») funded by the Labex Palm. This project aims at the optical control of nonlinear Josephson plasma waves in high-Tc superconducting cuprates by means of Terahertz light [1,2] in order to realize several analogues of nonlinear optics in the Terahertz (THz) frequency range (a timely issue for the development of technology in that frequency range). To that end, it is proposed to design and realize tuneable THz optical cavities that are strongly and resonantly coupled to Josephson plasma waves by structuring thin films of high-Tc superconductors [3]. This novel approach is used to facilitate their manipulation and extend the range of nonlinear control capabilities. The electromagnetic response of such THz cavity-superconductor metamaterials will be investigated by time domain THz spectroscopy, both in the linear and nonlinear regime of light-matter interaction.

 

Environnement: The applicant will be working on the development THz cavity-superconductor heterostructures in the clean room of the CNRS-Thales laboratory. This includes, among others, the structuring of materials with photolithography. The applicant will then characterize the metamaterials by THz time domain spectroscopy (in the linear and nonlinear regime) with the THz experimental setups of the Laboratoire des Solides irradiés at the Ecole Polytechnique.

Profile: We are looking for a talented and motivated postdoctoral researcher interested in this experimental condensed matter physics project. The applicant should have a PhD in experimental condensed matter physics. Device fabrication using clean room techniques and background knowledge in superconductivity will be a plus. A one-year position is available with possibility of extension. Starting date: as soon as possible. Application deadline: until the position is filled.
