Development of a multiphysics approach to model and simulate superconducting digital circuits

                                                                                                                                             
POST -DOCTORAL POSITION 2018-2019

The Laboratory of Microwave and Characterization (IMEP-LAHC, CNRS UMR 5130) of Université Savoie MontBlanc located in the French Alps area develops ultrafast energy-efficient superconducting digital circuits that work with clock frequencies of several tens of GHz, based on the Rapid Single-Flux Quantum (RSFQ) technology. Such circuits use a binary dynamic logic derived from the underlying physics of shunted Josephson junctions.
They require specific simulation and modeling tools to anticipate their behaviour as a function of several parameters, in different conditions of operation.
In the frame of the ColdFlux project developed between groups located in the United States of America, South Africa, Japan and France, we study the electrical, thermal and microwave properties of superconducting digital circuits.
The work is focused on the development of a multiphysics approach to predict the behaviour of circuits and build advanced SPICE-based models as well as dynamic libraries and TCAD modules to help the designer. All developed softwares will be open-source, compatible with tools developed by other partners of the project and ultimately available for other communities. The development of test benches based on the design of specific superconducting digital circuits is
planned to verify the proper operation of the suite of software tools.

The post-doctoral offer is for the January 2018-January 2019 period and is renewable for one more year.

A curriculum in Physics and an experience in the superconductivity field is necessary, as well a thorough knowledge of some programming languages (C/C++, Python, Fortran,…), low-level (TCAD and SPICE) and high-level (HDL) simulators and scientific sofwares (Matlab, COMSOL,…).

The net salary is around 2100€/month (social security, healthcare and pension plans are provided).

Applications must include a detailed CV with a list of of publications, a letter of motivation and letters of recommendation or references.
