Dr. Amir Burshtein received a Fulbright postdoctoral fellowship to theoretically investigate nonequilibrium dynamics in quantum many-body systems through the viewpoint of experiments in superconducting circuits.

Amir received a B.Sc. in physics and electrical engineering from the Technion – Israel Institute of Technology. He then completed an M.Sc. degree in physics and continued to his Ph.D. studies at Tel Aviv University, both under the supervision of Professor Moshe Goldstein. Amir is a theorist in the field of many-body quantum systems, aiming to understand how microscopic interacting particles conspire to form macroscopic collective phases that are mediated by the laws of quantum mechanics. Amir utilizes superconducting electrical circuits – the leading technology in the race for quantum computation – as a playground for the implementation and direct investigation of paradigmatic many-body models. The extraordinary, “unnatural” effects observed in superconducting circuits, such as the spontaneous high probability decay of single photons, turn out to be potent diagnostic tools that unveil unique perspectives on fundamental aspects of interacting quantum systems, including quantum tunneling, phase transitions, and decoherence. His theoretical works are directly related to concrete experimental setups yet also bear consequences across a wide range of topics.
