Identifies a zero-temperature spin relaxation channel via gyromagnetic coupling to Rayleigh vorticity that is super-Ohmic and depth-dependent, distinct from Raman processes.
Protocols for generating quantum resources can simultaneously charge quantum batteries with a collective advantage, enabling dual-use superconducting hardware for sensing or energy storage.
Warm 85Rb vapor produces high-flux twin beams with 5.5 dB squeezing and individual photon-number squeezing via near-degenerate SFWM at 795 nm, with flat-topped temporal correlations.
