Noise Induced Universal Diffusive Transport in Fermionic Chains
Christopher M. Langlett, Shenglong Xu
We develop a microscopic transport theory in a randomly driven fermionic model with and without linear potential. The operator dynamics arise from the competition between noisy and…
Charge transport, information scrambling and quantum operator-coherence in a many-body system with U(1) symmetry
Lakshya Agarwal, Subhayan Sahu, Shenglong Xu
In this work, we derive an exact hydrodynamical description for the coupled, charge and operator dynamics, in a quantum many-body system with U(1) symmetry. Using an emergent symme…
Extracting Quantum Many-Body Scarred Eigenstates with Matrix Product States
Shun-Yao Zhang, Dong Yuan, Thomas Iadecola +2
Quantum many-body scarred systems host nonthermal excited eigenstates immersed in a sea of thermal ones. In cases where exact expressions for these special eigenstates are not know…
Quantum Many-Body Scars from Einstein-Podolsky-Rosen States in Bilayer Systems
Julia Wildeboer, Christopher M. Langlett, Zhi-Cheng Yang +3
Quantum many-body scar states are special eigenstates of nonintegrable models with distinctive entanglement features that give rise to infinitely long-lived coherent dynamics under…
Orbital-Active Dirac Materials from the Symmetry Principle
Shenglong Xu, Congjun Wu
Dirac materials, starting with graphene, have drawn tremendous research interest in the past decade. Instead of focusing on the orbital as in graphene, we move a step further…
Nonsymmorphic bosonization in one-dimensional generalized Kitaev spin-1/2 models
Wang Yang, Chao Xu, Shenglong Xu +2
In this work, we perform a detailed study on the consequences of nonsymmorphic symmetries in the Luttinger phase of the one-dimensional spin-1/2 Kitaev-Heisenberg-Gamma model with…
