Post Doctoral Fellow (36054)

The Department of Physics of Northern Illinois University invites applications for a postdoctoral position in computational condensed matter theory. The successful applicants will start in the Spring 2025 semester and work on the project entitled "In-situ vortex manipulation and trapped flux removal in superconducting electronic devices", funded by Army Research Laboratory within the basic-research program "Foundation of Superconducting Digital Logic". The project is a collaborative effort between research groups located at Northern Illinois University (NIU), the University of Notre Dame, Argonne National Laboratory, The University of Bath (UK), and University of Antwerp (Belgium), respectively. The efforts at NIU are led by Prof. Andreas Glatz and involves seven PIs in total. The theoretical/computation aspects of the research include large-scale numerical simulations and theoretical analysis of vortex dynamics in patterned superconducting films. The goal is to develop efficient methods to remove trapped flux from superconducting electronic circuits. Position Summary Under the supervision of the NIU senior faculty and theory PIs of the project, the successful postdoctoral scholar will work on the theory and simulation of the dynamical processes in complex superconducting heterostructure relevant for superconducting digital logic devices. The obtained simulation results will be analyzed and verified with experimental observations in collaboration with the experimentalist in the project. The main focus is on the study of the dynamics of superconducting magnetic vortices and their control. A strong computational background is essential for the position. Research results should be prepared for publication in appropriate scientific journals. The conducted research will enhance the scholar's professional skill and research training to pursue his/her chosen career path.
