Fig. 1: Schematics of model phases, dynamics, and typical circuit realization.
From: Anomalous transport in U(1)-symmetric quantum circuits
Schematics showing a different regimes of our generic U(1)-symmetric model. Along the three solid borders the model is integrable; whilst the dashed border at Jz = π spans four distinct regimes, and is the region we predominantly address in this article. b shows the initial (dotted) and late-time (solid) spin magnetization profiles for different phases along the Jz = π line. c shows discrete time evolution as determined by a (periodic) U(1)-symmetric Floquet unitary \(\widehat{{\mathbb{U}}}\) comprised of nearest-neighbor gates.
