Universal Spin Squeezing Dynamical Phase Transitions across Lattice Geometries, Dimensions, and Microscopic Couplings
The study investigated universal spin squeezing dynamical phase transitions in bilayer XXZ spin models across various lattice geometries and interaction strengths. It found that this transition persists regardless of geometry or interlayer coupling ratio, proving the existence of a genuine non-equilibrium universality class for these power-law interacting systems.
