The spectroscopy of hot atomic vapours is a hot topic. Many of the work-horse techniques of
contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic …

We present a computer program and underlying model to calculate the electric susceptibility
of a gas, which is essential to predict its absorptive and dispersive properties. Our program …

A light, compact optical isolator using an atomic vapor in the hyperfine Paschen–Back
regime is presented. Absolute transmission spectra for experiment and theory through an …

Decoupling of total electronic and nuclear spin moments of Cs atoms in an external
magnetic field for the case of atomic D_1 line, leading to onset of the hyperfine Paschen …

We present a method for recovery of narrow homogeneous spectral features out of a broad
inhomogeneous overlapped profile based on second-derivative processing of the …

We investigate experimentally and theoretically the Faraday effect in an atomic medium in
the hyperfine Paschen–Back regime, where the Zeeman interaction is larger than the …

We have studied the peculiarities of selective reflection from an Rb vapor cell with a
thickness L< 70 nm, which is smaller than the length scale of evanescent fields λ/2π and …

The existence of crossover resonances makes saturated-absorption (SA) spectra very
complicated when external magnetic field B is applied. It is demonstrated for the first time, to …

The magnetic field-induced giant modification of probabilities for seven components of 6S
1/2, F g= 3→ 6P 3/2, F e= 5 transition of the Cs D 2 line, forbidden by selection rules, is …

In this article, we study the theoretical behaviour of all the possible hyperfine transitions (π,
σ+ and σ−) between the 5S and 6P states of 87 Rb and 85 Rb atomic vapors under the …
