Description du sujet de thèse

We are looking for someone to join the quantum matter group at LPEM to contribute to the design, implementation and operation of a state-of-the-art SQUID microscope. The scientific objective is to study and image non-Fourier regimes of heat transport at low temperatures. The aim of this project is to visualise the breakdown of Fourier's law, paving the way for the development of a more physically satisfactory model of heat propagation. To do this, we will be using a highly sensitive, spatially resolved thermometer, capable of probing the surfaces of materials with exceptional resolution to resolve heat propagation at the nanometric scale: the scanning SOT microscope. This microscope is unique in that it is the only one to have such high thermal and spatial resolution and to be able to operate at low temperatures (below 15 K), where most viscous hydrodynamics and other non-Fourier heat propagation phenomena have been observed.

Contexte de travail

You will be working in the centre of Paris. The laboratory is ideally located in the fifth arrondissement in a brand-new building. We have access to several characterisation platforms (SEM, clean room, AFM), a mechanical workshop and a helium liquefaction centre. Within the laboratory, you will interact with experts in low-temperature transport, scanning probes and thermal transport.

Contraintes et risques

The usual risks associated with the use of vacuum, cryogenics, electronics and standard chemical exposure (acetone, Stycast, etc.). The laboratory has all the necessary protective equipment and fume hoods.
