Collapse and revival of a Dicke-type coherent narrowing in potassium vapor confined in a nanometric-thin cell
A. Sargsyan, Y. Pashayan-Leroy, C. Leroy +1
A nanometer-thin-cell (in the direction of laser beam propagation) has been elaborated with the thickness of the atomic vapor column varying smoothly in the range of $L = \unit[50-…
Non-exponential Auger decay
A. M. Ishkhanyan, V. P. Krainov
We discuss the possibility of non-exponential Auger decay of atoms irradiated by X-ray photons. This effect can occur at times, which are greater than the lifetime of a system unde…
Spectroscopic detection of atom-surface interactions in an atomic vapour layer with nanoscale thickness
K. A. Whittaker, J. Keaveney, I. G. Hughes +3
We measure the resonance line shape of atomic vapor layers with nanoscale thickness confined between two sapphire windows. The measurement is performed by scanning a probe laser th…
Electromagnetically induced transparency resonances inverted in magnetic field
A. Sargsyan, D. Sarkisyan, Y. Pashayan-Leroy +4
The electromagnetically induced transparency (EIT) phenomenon has been investigated in a -system of the Rb D line in an external transverse magnetic field. Two spectr…
Complete hyperfine Paschen-Back regime at relatively small magnetic fields realized in Potassium nano-cell
A. Sargsyan, A. Tonoyan, G. Hakhumyan +3
A one-dimensional nano-metric-thin cell (NC) filled with potassium metal has been built and used to study optical atomic transitions in external magnetic fields. These studies bene…
