Shachar
Fraenkel

Shachar Fraenkel is a PhD student in the Raymond and Beverly Sackler School of Physics and Astronomy at Tel Aviv University under the supervision of Prof. Moshe Goldstein.

Shachar research lies at the intersection between quantum information theory and quantum condensed matter theory, as he employs mathematical tools developed under the umbrella of the former to address fundamental problems within the latter.

Condensed matter theory deals with many-body systems, i.e., systems comprised of many microscopic particles that produce complex behaviours through their intercorrelations. In this context, Shachar mainly studies the entanglement properties of quantum many-body systems. Entanglement is a type of correlation between particles that is unique to quantum systems and defies classical intuition, providing a universal framework for the study of collective phenomena in such systems. Shachar analyzes entanglement in canonical theoretical models, hoping to elucidate its connection to foundational questions in quantum many-body physics, related to phase transitions, symmetries, and many-body systems out of equilibrium.

Shachar was born and raised in Haifa and currently lives in Tel Aviv. He received his BSc in mathematics and physics from Tel Aviv University. Alongside his research, Shachar teaches undergraduate physics courses at the university. He also previously taught middle- schoolers preparing to compete in the Physics Olympiad and worked as a personal tutor in Tel Aviv University’s support centre for students with learning disabilities. In his free time, Shachar enjoys photography, plays tennis, and has a deep interest in cinema, literature, history, and classical music.
