Dr. Erez Zohar

I am a senior lecturer (assistant professor) at the Racah Institute of Physics, at the Hebrew University of Jerusalem, Israel. My research focuses on the interface between quantum many body theories and quantum information and optics, mostly in developing tools for dealing with strongly correlated systems and their application to particle physics. Besides that, I am generally interested in quantum mechanics, quantum field theory and mathematical physics.

November 2023:
Erez has won the ERC Consolidator Grant, given by the European Research Council, for the project OverSign - overcoming the sign problem in lattice gauge theories!

In our group, we aim at designing new tools, methods and approaches for solving difficult problems in many-body physics. On the process, we get to reconstruct physical models out of elementary ingredients (such as in the construction of tensor network states) or different building blocks (as in the design of a quantum simulator). In the process of reconstructing a theory from scratch, we get to learn a lot about it, to see it from new perspectives, to understand it better and to take it to new directions.
