Superdiffusive transport protected by topology and symmetry in all dimensions
Shaofeng Huang, Yu-Peng Wang, Jie Ren +1
Superdiffusion is an anomalous transport behavior. Recently, a new mechanism, termed the ``nodal mechanism," has been proposed to induce superdiffusion in quantum models. However,…
Quasi-Nambu-Goldstone modes in many-body scar models
Jie Ren, Yu-Peng Wang, Chen Fang
From the quasisymmetry-group perspective [Phys. Rev. Lett. 126, 120604 (2021)], we show the universal existence of collective, coherent modes of excitations in many-body scar model…
Superdiffusive transport on lattices with nodal impurities
Yu-Peng Wang, Jie Ren, Chen Fang
We show that 1D lattice models exhibit superdiffusive transport in the presence of random "nodal impurities" in the absence of interaction. Here a nodal impurity is defined as a lo…
Superdiffusive Transport in Quasi-Particle Dephasing Models
Yu-Peng Wang, Chen Fang, Jie Ren
Investigating the behavior of noninteracting fermions subjected to local dephasing, we reveal that quasi-particle dephasing can induce superdiffusive transport. This superdiffusion…
