Unveiling the Electronic Origin of Anomalous Contact Conductance in Twisted Bilayer Graphene

This study theoretically demonstrates that the anomalous non-monotonic contact conductance peak in twisted bilayer graphene at approximately 5° arises from the angle-dependent evolution of electronic band structure and van Hove singularities near the Fermi level, rather than from structural relaxation or AA-stacking variations.

Orbital-angular-momentum control of localized Floquet states and photocurrents in Weyl semimetals

This paper establishes that optical orbital angular momentum from vortex beams can generate highly localized Floquet vortex states with strong circulating photocurrents in Weyl semimetals, providing a real-space framework for controlling these current-carrying states through the light's spatial profile.

Adiabatic confinement and number-theoretic spectra of massless Dirac fermions in twisted trilayer graphene

This paper demonstrates that smooth stacking variations in twisted trilayer graphene create adiabatic confinement of massless Dirac fermions within equilateral triangular Bernal domains, forming quantum cavities whose energy spectra exhibit striking oscillations governed by Eisenstein-integer arithmetic and number-theoretic principles.
