Spin Accumulation and Longitudinal Spin Diffusion of Magnets
Wayne M. Saslow, Chen Sun, Shenglong Xu
We extend to the longitudinal component of the magnetization the spintronics idea that a magnet near equilibrium can be described by two magnetic variables. One is the usual magnet…
Emergent Symmetry in Brownian SYK Models and Charge Dependent Scrambling
Lakshya Agarwal, Shenglong Xu
In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite and in the infinite limit. We comp…
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…
