Scanning SET Microscopy
in a Dry Dilution Refrigerator
A millikelvin scanning SET/MIM platform is being developed to image local compressibility, electrostatic potential, and fractional charge in correlated and topological moiré materials.
Microwave Impedance Microscopy of Fractional Chern Insulators
Microwave Impedance Microscopy of Fractional Chern Insulators
The bulk–edge correspondence is directly imaged in a fractional Chern insulator at zero magnetic field with exciton-resonant microwave impedance microscopy (MIM), revealing spatially resolved bulk and edge characteristics, and the evolution of topological states in twisted MoTe2
Nature 635, 578-583 (2024)
Fractional Quantum Anomalous Hall Effect
Fractional Quantum Anomalous Hall Effect
Transport measurements in twisted bilayer MoTe2 reveal quantized Hall resistance plateaus and composite Fermi liquid-like behaviour under zero magnetic field,
a direct observation of integer and fractional quantum anomalous Hall effects
Bose-Hubbard Model
of Moiré Exciton Lattices
Bose-Hubbard Model
of Moiré Exciton Lattices
Strong dipole–dipole interactions between excitons in a moiré superlattice
create a manifestation of the Bose–Hubbard model
with a ground state similar to a Mott insulator
Nature Physics 19, 1286-1292 (2023)
