Non-linear density scaling of spin noise reveals atomic correlations in warm vapors
Joseph Delpy, Elwyn Cardoz, Adwaith KV +4
We experimentally demonstrate a non-linear dependence of the spin noise variance on atomic density in a warm alkali vapor. Implementing high-bandwidth spin noise spectroscopy (SNS)…
Anomalous high-density spin noise in a strongly interacting atomic vapor
J. Delpy, N. Fayard, F. Bretenaker +1
Spin noise spectroscopy (SNS) has become a mainstream approach to probe the dynamics of a spin ensemble in and out of equilibrium. Current models describing spin noise in interacti…
Long-range interactions revealed by collective spin noise spectra in atomic vapors
J. Delpy, N. Fayard, F. Bretenaker +1
We report anomalous features in the spin noise spectroscopy (SNS) of a thin cell of a dense vapor of alkali atoms. At high densities and close to resonance, we observe a dramatic b…
Creation and dynamics of spin fluctuations in a noisy magnetic field
J. Delpy, S. Liu, P. Neveu +4
We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a stan…
Spin noise spectroscopy of optical light shifts
Joseph Delpy, Shikang Liu, Pascal Neveu +3
Light induced non-equilibrium spin noise spectroscopy is theoretically and experimentally shown to be an efficient technique to reveal the structure and the coherent effects in the…
Birefringence and dichroism effects in the spin noise spectra of a spin-1 system
S. Liu, P. Neveu, L. Hemmen +4
We perform spin noise spectroscopy experiments in metastable helium atoms at room temperature, with a probe light whose frequency is blue detuned from the D0 line. Both circular bi…
