Condensed Matter Seminar: Semiconductor Moiré 2.0
Speaker Prof. Kin Fai Mak, Cornell University
Date 27 May 2021 (Thursday)
Time 10:00 - 11:30
Venue Online (Zoom)

Semiconductor moiré materials realize a highly tunable platform for simulating Hubbard model physics on a triangular lattice. To date experimental studies have focused on the non-topological, flat band limit, where Mott insulators, Wigner crystals and stripe phases have been demonstrated. In this talk, I will discuss how tunable electronic correlations and nontrivial band topology can greatly enrich the electronic phase diagram of the system. Specifically, I will discuss the continuous Mott transition from a non-magnetic Mott insulator to a Fermi liquid and the experimental realization of the Kane-Mele-Hubbard model.
