In our recently published paper we show that Dirac fermions do not like to get their speed to zero, unless they really have to. Knowing how many knobs we need to fine-tune lays the foundation to find new topological flat bands with the possibility for exotic correlated phases:
New demonstrations of superconductivity in multilayer stacks of graphene continue to emerge, even as researchers struggle to explain how it all works.

Nishchhal Verma join us as a postdoc. Nish is interested in the interplay between topology and superconductivity in quantum materials, among many other things. We are delighted to have you join the team, Nish!
Jointly with Prof. Andrew Millis the topological matter group is searching for a new postdoctoral scientist interested in topological and strongly correlated properties of moire heterostructures. Don't hesitate to contact me if you are interested or know of any interested candidates.
Applications are encouraged to arrive before September 30.
I am very pleased to announce that our Topological Quantum Matter online courseis finally live! A project with my colleagues and friends at Weizmann Institute.

Press release in Science Daily of the beautiful experimental and theoretical collaboration to understand the phase diagram of twisted bilayer graphene. Toguether with Shahal Ilani, Erez Berg, Yuval Oreg, Felix von Oppen and Ady Stern, we discover a cascade of first order phase transitions that define the parent state of the electronic states at different densities.
