Retarded interaction between opposite chiral edges in anomalous Hall crystals
Wangqian Miao, Mu-Yang Chen, Binghai Yan +1
An anomalous Hall crystal combines spontaneous electronic crystallization with a Chern insulating gap, supporting both chiral edge modes and low-energy electronic phonons. We show…
Multi-Knob Switchable Chiral Superconductivity Quartet in Rhombohedral Graphene
Zhenqi Hua, Shenyong Ye, Phatthanon Pattanakanvijit +17
Chiral superconductors break orbital time-reversal symmetry and may host topological quasiparticles with non-Abelian statistics. In rhombohedral graphene, superconductivity develop…
Orbital Magnetization from Uniform and Periodic Magnetic Fields
Chunli Huang
Magnetization is thermodynamically defined as the derivative of the grand potential with respect to a uniform magnetic field. However, a uniform magnetic field makes the kinetic mo…
Two-Body Solution and Instabilities along Streda Lines in Moire Flat Bands
Guopeng Xu, Chunli Huang
Moire minibands in twisted homobilayer semiconductors can, under suitable approximations, be modeled as a pair of Landau levels with opposite Chern numbers. This provides a minimal…
Localized Excitons and Landau-Level Mixing in Time-Reversal Symmetric Pairs of Chern Bands
Guopeng Xu, Nemin Wei, Inti Sodemann Villadiego +1
We study Landau-level mixing in a time-reversal-symmetric Hamiltonian composed of two sets of Landau levels with opposite magnetic field, relevant to moiré minibands in twisted ho…
Elementary Excitations, Melting Temperature and Correlation Energy in Wigner Crystal
Ambuj Jain, Chunli Huang
We present a fully quantum-mechanical study of the energy-momentum dispersion of running waves, spin-conserving neutral excitations, and spin-reversal neutral excitations in a spin…
