Fractional Topological Insulator and Topological Superconductor in TMD Moire Bilayers
Fractional Topological Insulator and Topological Superconductor in TMD Moire Bilayers
10:20 - 11:20
Room: 310
Bilayer transition metal dichalcogenide (TMD) bilayers have offered unprecedented opportunities for experimental discoveries of novel topological states without a magnetic field. In my talk, I will first give a brief overview of the field of fractional Chern insulators (FCI) and present numerical evidence of the emergence of a non-Abelian FCI for twisted MoTe2 system at the fractional hole filling of 3/2. I will show you signatures of a non-Abelian state via exact diagonalization calculations, including a stable six-fold ground-state degeneracy and fractionally quantized Chern number that are consistent with an even-denominator FCI. In the second part of my talk, I will focus on experimental platforms of hetero-TMD bilayers, and present numerical evidence for the emergence of chiral spin liquid and topological d+id superconductivity. Our findings highlight the richness of the TMD Moire platforms for discovering correlated topological states of matter.
