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)…

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…
