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)…
Collective-Coordinate Fluctuations of Driven-Dissipative Solitons
Yifan Sun, Thomas Bunel, Sofya Glazyrina +5
Fluctuations of nonequilibrium localized waves are shaped not only by direct stochastic forcing but also by deterministic transfer among coupled collective degrees of freedom. We d…
Bridging gaps in Rydberg RF receivers using modulation transfer bandwidth enhancement
Mickael Branco, K V Adwaith, Gabriel Boccara +5
We optimize theoretically and experimentally the performances of the recently demonstrated modulation transfer protocol [D.-A. Trinh, K. V. Adwaith, M. Branco, A. Rouxel, S. Welins…
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…
