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…
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…
Observation of Electromagnetically Induced Transparency and Slow Light in the Dark State - Bright State Basis of CPT
T. Lauprêtre, J. Ruggiero, R. Ghosh +2
Electromagnetically induced transparency (EIT) is observed in a three-level system composed of an excited state and two coherent superpositions of the two ground-state levels. This…
Realistic theory of electromagnetically-induced transparency and slow light in a hot vapor of atoms undergoing collisions
Joyee Ghosh, R. Ghosh, F. Goldfarb +2
We present a realistic theoretical treatment of a three-level system in a hot atomic vapor interacting with a coupling and a probe field of arbitrary strengths, leading to elec…
