Jonathan Ruhman

Theory of Quantum Condensed Matter

Important Anouncement:
FRONTIERES in Dynamics of quantum information

We will host a special series of virtual seminars every Thursday at 4pm (GMT+2) between April 22nd and May 27th (Registration link). For more information click here.

Research interest:

Our group studies open questions in quantum condensed matter physics using theoretical tools. We are located at the Physics department of Bar Ilan university, Israel, where we currently focus on the following problems:

- Superconductivity in low-density systems (SrTiO3, topological semimetals, etc.) - microscopics and phenomenological theory
- Dynamics of quantum information in chaotic many-body systems
- Topological superconductivity.
- Transport in strongly coupled liquids
- vdW heterostrcutres, twisted bilayers etc.
