Grab it Explore the intricacies of layer pseudospin magnetism and electric field induced anomalous Hall effects in rhombohedral multilayer graphene in this 35-minute lecture by Jeil Jung from PCS Institute for Basic Science. Delve into recent experimental findings revealing Coulomb interaction driven gapped phases in dual gated rhombohedral multilayer graphene devices, with a focus on pentalayer and tetralayer structures exhibiting spontaneous gaps due to layer pseudospin polarization. Examine the various manifestations of layer pseudospin polarization and their impact on Hall conductivities. Investigate the self-consistent solutions for different pseudospin magnetic phases using mean-field Hartree-Fock approach. Consider the effects of spin-orbit coupling and moire potentials on the system's ground state, including the potential for CDW gaps with fractional filling densities. Conclude with a discussion on the energetics of spontaneous spin-valley polarization in the presence of carrier doping and perpendicular electric fields in a moire-less system. Read more
