Symmetry-protected dissipative spin squeezing is realized in the resolved vacuum Rabi splitting regime for 87Sr atoms via ramped drives, achieving over 25 dB squeezing for 10^5 atoms close to ideal one-axis twisting scaling.

Using the truncated Wigner approximation on large 1D and 2D systems, the authors find a pronounced slowdown in magnetization relaxation and transient signatures of quantum kinetically constrained dynamics starting from polarized and Néel states.
Theoretical proposal for cavity-based momentum-state spin squeezing in Bragg interferometers that models momentum width and off-manifold coupling and predicts feasible squeezing levels with current technology.
