Abstract

Electron transport driven by the phase coherence and interference of quantum many-body wavefunctions is a fascinating phenomenon with potential technological significance. This work proposes a momentum-space analog of the AC Josephson effect in the intervalley coherent (IVC) state of rhombohedral multilayer graphene under a static magnetic field, deriving phase-number dynamics, orbital magnetization oscillations, and an AC Hall response. Microscopic estimates are given for the free-energy parameters and characteristic oscillation frequency, with discussion of extensions to other 2D materials.
