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…
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…
Rainbow Scars: From Area to Volume Law
Christopher M. Langlett, Zhi-Cheng Yang, Julia Wildeboer +3
Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking. One open question is to understand th…
Hilbert Space Fragmentation and Exact Scars of Generalized Fredkin Spin Chains
Christopher M. Langlett, Shenglong Xu
In this work, based on the Fredkin spin chain, we introduce a family of spin- many-body Hamiltonians with a three-site interaction featuring a fragmented Hilbert space with co…
