Giant orbital magnetic moments and paramagnetic shift in artificial relativistic atoms and molecules
Electrostatically defined quantum dots in graphene constitute a testbed to study atomic and molecular physics in the ultrarelativistic regime—when the particle speed is close to the speed of light. Magnetic-field-dependent tunnelling spectroscopy experiments now reveal giant orbital magnetic moments and paramagnetic shifts in single and double quantum dots due to their relativistic nature.

Graphene moiré superlattices with giant quantum nonlinearity of chiral Bloch electrons
Graphene has a centrosymmetric crystal symmetry, which prohibits second-order effects in transport experiments. Yet, giant second-order nonlinear transports can emerge in graphene moiré superlattices at zero magnetic field, originating from the skew scattering of chiral Bloch electrons in the superlattice and giving rise to both longitudinal and transverse nonlinear conductivities under time-reversal symmetry.
