The researchers here shed new light on the elusive single-particle model of twisted bilayer MoTe${}_{2}$, a material recently highlighted for hosting fractional Chern insulators at zero magnetic field. By leveraging an advanced machine learning method and density functional theory, team meticulously maps out band structure across various twist angles, revealing pivotal inversion refining theoretical landscape. enhancing continuum with higher harmonic terms, they unveil opposite numbers in...
The observation of fractional Chern insulators in rhombohedral pentalayer graphene twisted on hexagonal boron nitride has initiated a flurry theoretical work seeking its explanation. As step towards understanding the origin these phases, authors undertake here first-principles study large family multilayer graphene/boron superlattices, including structural relaxation. moir\'e models they obtain faithfully capture microscopic band structure and are starting point for observed topological...
The I – V characteristics and critical current density at different temperatures have been carried out with a highly (100) oriented superconducting polycrystalline film. It is found that c = (0)(1 t) 2 , which similar to of network constructed ideal SNS junctions. At temperature T(kT) below the individual grains transition T c0 coherent will occur because coupling energy between begins be larger than thermal fluctuating energy. According Halperin-Nelson theory, we estimate 81.1 K behaviors...
