Single-Particle Decoherence Can Improve Spin-Squeezing Generated In Collective Dynamics
K. Tucker, D. Barberena, R. J. Lewis-Swan +3
We study the generation of spin-squeezing in arrays of long-lived dipoles subject to collective emission, coherent drive, elastic interactions, and spontaneous emission. Counter-in…

Shattered Time: Can a Dissipative Time Crystal Survive Many-Body Correlations?
Kristopher Tucker, Bihui Zhu, Robert J. Lewis-Swan +4
We investigate the emergence of a time crystal in a driven-dissipative many-body spin array. In this system the interplay between incoherent spin pumping and collective emission st…
