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…
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…
