Interaction-enhanced double resonance in cold gases
Alexander Safonov, Irina Safonova, Igor Yasnikov
A new type of double-resonance spectroscopy of a quantum gas based on interaction-induced frequency modulation of a probe transition has been considered. Interstate interaction of…
Comment on "Clock Shift in High Field Magnetic Resonance of Atomic Hydrogen"
A. I. Safonov, I. I. Safonova, I. S. Yasnikov
In this Comment, we reanalyze the experiments on the collision frequency shift of the b-c and a-d hyperfine transitions in three-dimensional atomic hydrogen in the presence of, res…
Hyperfine frequency shift in two-dimensional atomic hydrogen
A. I. Safonov, I. I. Safonova, I. S. Yasnikov
We propose the explanation of a surprisingly small hyperfine frequency shift in the two-dimensional (2D) atomic hydrogen bound to the surface of superfluid helium below 0.1 K. Owin…
