Fast generation of time-stationary spin-1 squeezed states by non-adiabatic control (2109.12168v1)
Published 24 Sep 2021 in cond-mat.quant-gas
Abstract: A protocol for the creation of time-stationary squeezed states in a spin-1 Bose condensate is proposed. The method consists of a pair of controlled quenches of an external magnetic field, which allows tuning of the system Hamiltonian in the vicinity of a phase transition. The quantum fluctuations of the system are well described by quantum harmonic oscillator dynamics in the limit of large system size, and the method can be applied to a spin-1 gas prepared in the low or high energy polar states.
