In the topological heavy fermion model, the Mott semimetal phase hosts well-defined quasiparticles with dispersion and relaxation rate proportional to the interaction strength.
A new theoretical framework enables the quantum twisting microscope to perform momentum-resolved spectroscopy of superconductivity, extracting pairing magnitude and symmetry from tunneling channels in 2D materials.
DFT study of relaxed twisted bilayer graphene structures and bands for twist angles down to 0.987 degrees, with good agreement to continuum models except for a small angle offset.
