JFI Colloquium - Jie Shan, Cornell University - 2D Moiré Quantum Materials

3:45–4:45 pm GCIS W301/W303

929 E. 57th Street

When two van der Waals materials of slightly different orientations or lattice constants are overlaid, a moiré pattern emerges. The moiré pattern introduces a new length scale (many times the lattice constant of the original materials) and periodic potentials. This strongly suppresses the kinetic energy of the electrons and gives rise to rich strongly correlated electron phenomena. In this talk, I will review recent progress on the development of 2D semiconductor moiré materials and realization of different many-body Hamiltonians. I will also discuss the opportunities and challenges in designing moiré materials and developing quantum simulators based on these artificial 2D materials.
