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…
Dual frequency caesium spin maser
Patrick Bevington, Rafal Gartman, Yevgeny V. Stadnik +1
Co-magnetometers have been validated as valuable components of the atomic physics toolbox in fundamental and applied physics. So far, the explorations have been focused on systems…
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…
Enhanced material defects imaging with a radio-frequency atomic magnetometer
P. Bevington, R. Gartman, W. Chalupczak
Imaging of structural defects in a material can be realized with a radio-frequency atomic magnetometer by monitoring the material's response to a radio-frequency excitation field.…
Imaging of material defects with a radio-frequency atomic magnetometer
P. Bevington, R. Gartman, W. Chalupczak
Non-destructive eddy current testing of defects in metal plates using the magnetic resonance signal of a radio-frequency atomic magnetometer is demonstrated. The shape and amplitud…
