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,…

Superdiffusive transport in chaotic quantum systems with nodal interactions
Yu-Peng Wang, Jie Ren, Sarang Gopalakrishnan +1
We introduce a class of interacting fermionic quantum models in dimensions with nodal interactions that exhibit superdiffusive transport. We establish non-perturbatively that t…

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…
