Offer Description We are looking for a postdoc (experimentalist) to join the quantum matter team at LPEM to work on the design and implementation of a SQUID-on-tip (SOT) microscope.
The position is funded by the ERC project THERMOSCOPY (2025-2030), whose scientific goal is to study and image non-Fourier regimes of heat transport at low temperatures. This project aims to visualize the breakdown of Fourier's law, paving the way for the development of a more physically satisfying model of heat propagation. The investigation will focus on a specific and very illustrative non-Fourier transport regime that has recently attracted considerable interest in the scientific community: the viscous hydrodynamic regime.
This will be done using a highly sensitive and spatially resolved thermometer, capable of probing material surfaces with exceptional resolution to resolve heat propagation at the nanoscale: the scanning SOT microscope. It is quite unique as it is the only one with such thermal and spatial resolution that can operate at low temperatures (below 15K), where most of the viscous hydrodynamic regime and other non-Fourier heat propagation phenomena have been observed.
You will be involved in the fabrication of SOT together with their low temperature characterization, the design, implementation, and control of the scanning microscope, and finally the preparation of samples to be scanned. You will participate in the measurements campaign and their analysis.
You will work in the center of Paris. The laboratory is ideally located in the fifth district in a brand new building. We have access to several characterization platforms (MEB, Clean room, AFM), mechanical workshop, and helium liquification center. In the lab, you will interact with experts in low temperature transport, scanning probe, and thermal transport.
You have a PhD degree in condensed matter physics or quantum physics. You enjoy teamwork, are rigorous and pragmatic. You are fluent in scientific English. You have proven experience in various of the following fields:
Josephson/SQUID physics
Scanning probe measurements (STM, AFM...)
Cryogenics
3D object design
Thin film deposition
Lithography, work in clean room
