We report an experimental and theoretical study of spin-noise correlations in a Rb 87-Cs
133 unpolarized alkali-metal vapor dominated by spin-exchange collisions. We observe …

Ensembles of alkali-metal or noble-gas atoms at room temperature and above are widely
applied in quantum optics and metrology owing to their long-lived spins. Their collective spin …

Collision phenomena are ubiquitous and highly useful in determining the microscopic
structures and intermolecular interactions of atoms and molecules. The existing approaches …

Spin-exchange collisions in alkali or alkali-noble gas vapors are at the basis of quantum
sensing, nucleon structure studies, tests of fundamental symmetries, and medical imaging …

We present a theoretical and experimental paper of the zero-field optical spin noise (OSN)
spectrum for a thermal state alkali vapor in the strong spin-exchange coupling regime. We …

Characterization of microstructures in living tissues is one of the keys to diagnosing early
stages of pathology and understanding disease mechanisms. However, the extraction of …

The spin dynamics in a thermal atomic vapor cell have been investigated thoroughly over
the past decades and have proven successful in quantum metrology and memory owing to …

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 …

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 …

We perform spin noise spectroscopy close to resonance in a 1-mm-thick cell containing a
dense Rubidium vapor. A laser is used to excite optical dipoles in the vapor while probing …
