Theory of Half-Integer Fractional Quantum Spin Hall Insulator Edges
Julian May-Mann, Ady Stern, Trithep Devakul
We study the edges of fractional quantum spin Hall insulators (FQSH) with half-integer spin Hall conductance. These states can be viewed as symmetric combinations of a spin-up and…

Crystalline axion electrodynamics in charge-ordered Dirac semimetals
Julian May-Mann, Mark R. Hirsbrunner, Lei Gioia +1
Three-dimensional Dirac semimetals can be driven into an insulating state by coupling to a charge density wave (CDW) order. Here, we consider the quantized crystalline responses of…

Multi-moiré trilayer graphene: lattice relaxation, electronic structure, and magic angles
Charles Yang, Julian May-Mann, Ziyan Zhu +1
We systematically explore the structural and electronic properties of twisted trilayer graphene systems. In general, these systems are characterized by two twist angles, which lead…
