InstituteQ Colloquium: Dmitri Efetov of Ludwig-Maximilians-Universität München

When: 28.08.2023
Where: Aalto University, Konetekniikka 1, hall 216

InstituteQ’s next Colloquium features insights from Professor Dmitri Efetov, with a focus on magic angle twisted bilayer graphene. The Colloquium will be held at 15:00 on Monday, August 28 at Konetekniikka 1, hall 216.

Topic

In his talk, Efetov will introduce the main concepts underlying recent discoveries of novel many-body ground states in moiré systems. These include correlated insulators, unconventional superconductivity, strange metals, orbital magnetism, and topologically nontrivial phases.

With a focus on magic angle twisted bilayer graphene, Efetov will show how symmetry-broken states emerge at all integer electron fillings. In addition, he will also discuss recent experiments, including: screened interactions, Chern insulators, magnetic Josephson junctions, quantum criticality, re-entrant correlated insulators at high magnetic fields, Dirac spectroscopy of correlated states in magic angle trilayers, and the avenues for novel quantum sensing applications.

Guest speaker

Efetov received his PhD in Physics from Columbia University in 2014 with a thesis titled “Towards inducing superconductivity into graphene,” and then went on to work as a postdoctoral researcher at the Massachusetts Institute of Technology, developing ultra-fast microwave thermometry and single photon detectors based on graphene. Efetov has served as a full professor and Chair of Solid State Physics at LMU Munich since 2021.
