Spin noise spectroscopy of a noise-squeezed atomic state
V. Guarrera, R. Gartman, G. Bevilacqua +1
Spin noise spectroscopy is emerging as a powerful technique for studying the dynamics of various spin systems also beyond their thermal equilibrium and linear response. Here, we st…
Linear and non-linear coherent coupling in a Bell-Bloom magnetometer
R. Gartman, V. Guarrera, G. Bevilacqua +1
Spin-exchange collisions in hot vapours are generally regarded as a decoherence mechanism. In contrast, we show that linear and non-linear spin-exchange coupling can lead to the ge…
Parametric amplification and noise-squeezing in room temperature atomic vapours
V. Guarrera, R. Gartman, G. Bevilacqua +2
We report on the use of parametric excitation to coherently manipulate the collective spin state of an atomic vapour at room temperature. Signatures of the parametric excitation ar…
