Cavity-mediated all-to-all interactions in a solid-state 171Yb3+:CaWO4 ensemble enable superradiance, one-axis twisting, and gap-protected coherence extending Ramsey times from microseconds to milliseconds.
The maximum photon emission rate in atomic ensembles scales universally as atom number times optical depth at fixed density, unifying ordered and disordered systems from independent emission to the Dicke limit.
Optimal cavity modulation via Krylov theory extends qubit lifetime in inhomogeneous spin ensembles by an order of magnitude over inhomogeneity and cavity losses.
Ordered subwavelength 2D atomic arrays exhibit many-body super- and subradiance, spatial correlations, superradiant scaling and revivals, and ferromagnetic/antiferromagnetic character in collective decay.
Quantum Mpemba effect in Markovian open quantum systems can be realized via decoherence-free subspaces with decay rates that scale exponentially with system size, plus subtleties revealed by Davies map unravelings.
