-shift in a short-baseline atomic interferometer-gravimeter
D. N. Kapusta, A. E. Bonert, A. N. Goncharov +6
This paper presents the first experimental observation and investigation of a lineshape-asymmetry-caused shift (LACS) in a short-baseline atomic interferometer-gravimeter. It is sh…
Lineshape-asymmetry-caused shift in atomic interferometers
V. I. Yudin, O. N. Prudnikov, A. V. Taichenachev +7
We investigate the shift caused by asymmetry of spectroscopic lineshape in atomic interferometers, which has not previously been discussed in the scientific literature. This asymme…

We develop a field-nonlinear theory of sub-Doppler spectroscopy in a gas of two-level atoms, based on a self-consistent solution of the Maxwell-Bloch equations in the mean field an…
Probe field ellipticity-induced shift in an atomic clock
V. I. Yudin, A. V. Taichenachev, O. N. Prudnikov +5
We investigate the probe field induced shift for atomic lattice-based and ion-trap clocks, which can be considered as a near resonant ac-Stark shift, connected to the Zeeman struct…
Atomic-motion-induced spectroscopic effects nonlinear in atomic density in a gas
V. I. Yudin, A. V. Taichenachev, M. Yu. Basalaev +2
The interatomic dipole-dipole interaction is commonly thought to be the main physical reason for spectroscopic effects nonlinear in atomic density. However, we have found that the…
