Theory of Quantum Condensed Matter

Research interest:

We are a theoretical research group in the field of quantum condensed matter physics. 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.
