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…
