Multicomponent Magnetic Domain Walls in Rhombohedral Graphene
Mainak Das, Nemin Wei, Chunli Huang
Spatial textures of magnetic order, such as domain walls and skyrmions, are fundamental objects in magnetism. In rhombohedral multilayer graphene, magnetic order involves spin and…
Momentum-Space AC Josephson Effect and Intervalley Coherence in Multilayer Graphene
Mainak Das, Chunli Huang
Electron transport driven by the phase coherence and interference of quantum many-body wavefunctions is a fascinating phenomenon with potential technological significance. Supercon…
Superpolarized Electron-Hole Liquid and Multiferroicity in Multilayer Graphene
Mainak Das, Chunli Huang
We introduce a many-body state termed superpolarized electron-hole liquid to explain the multiferroic properties observed in a recent experiment on rhombohedral pentalayer graphene…
Quarter-Metal Phases in Multilayer Graphene: Ising-XY and Annular Lifshitz Transitions
Mainak Das, Chunli Huang
Recent experiments have uncovered a distinctive magnetic metal in lightly-doped multilayer graphene, coined the \textit{quarter metal}. This quarter metal consolidates all the dope…
