Direct magnetometry imaging establishes reconfigurable chiral superconductivity in rhombohedral graphene with low-current domain control.
Chiral Bloch states in rhombohedral n-layer graphene cause high-harmonic generation whose dominant order scales linearly with n, with valley splitting producing n-dependent circular dichroism.
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.
Higher-order k corrections to Dirac dispersion enable Kohn-Luttinger superconductivity, producing topological p-ip pairing in broken-TR systems and anisotropic or warped pairings on TI surfaces.
A microscopic tunneling approach is developed showing that scanning tunneling spectroscopy can distinguish commensurate and incommensurate single-q pairing states and a three-q moiré superconductor in rhombohedral graphene via broken time-reversal symmetry features and spatial Andreev conductance.
Theory for QPI in chiral-band superconductors shows impurity-induced local spectral functions distinguish zero- and finite-momentum pairing states.
