Universal Spin Squeezing Dynamical Phase Transitions across Lattice Geometries, Dimensions, and Microscopic Couplings
Arman Duha, Thomas Bilitewski
Recent work has identified a dynamical squeezing phase transition in power-law interacting bilayer XXZ spin models, separating a fully collective phase with Heisenberg-limited sque…

Scalable spin-nematic squeezing in multi-level dipole-interacting Rydberg atom arrays
Sakshi Bahamnia, Thomas Bilitewski
We study the generation of metrologically useful entanglement in a three-level (spin-1) system naturally realized in arrays of dipole-interacting Rydberg atoms confined in optical…

Nonequilibrium Critical Scaling of a Squeezing Phase Transition
Arman Duha, S. E. Begg, Thomas Bilitewski
We investigate phase transitions in the nonequilibrium dynamics of power-law interacting spin-1/2 bilayer XXZ models, which have recently been shown to allow generation of entangle…
