WebSuperfluid 3He-A confined in a slab of small enough width exhibits an effect analogous to the quantization of the Hall conductance σxy. The factor σxy in the supercurrent transverse to the applied gradient of the chemical potential, j =σ xy l ×∇μ , is a topological invariant; σ xy =( 1 2 h)n , where the integer n corresponds to the number of transverse energy levels … WebApr 6, 2024 · Because the magic-angle flat band quasiparticles are isolated from remote band quasiparticles only for effective dielec.consts.larger than ∼20, the gapped states do not necessarily break C2T symmetry and as a consequence the insulating states at n = ±1/4 and n = ±3/4 need not exhibit a quantized anomalous Hall effect.
