Abstract: Interacting electrons in strong magnetic fields give rise to rich phenomena, exemplified by the quantum Hall effect. In rhombohedral graphene, remarkably similar behavior has been observed even without an external field. In this talk, I will describe how electron–electron interactions in this system can spontaneously generate giant effective magnetic fields, reaching hundreds of Tesla. These emergent fields originate from self-organized layer-skyrmion textures, whose dynamics give rise to distinctive collective shape modes that can be experimentally probed. Strikingly, much of this physics can be captured analytically in an “ideal limit”, revealing precisely how interactions can reproduce the essential ingredients of quantum Hall physics - without any external magnetic field.
