Loading of the narrow line Tm MOT from a pulsed cold atomic beam
M. Yaushev, D. Mishin, D. Tregubov +2
We report on building a pulsed source of cold Tm atoms and loading of the narrow-line magnito-optical trap (MOT) from the cold atomic beam. We achieve the loading rate of the first…
Synchronous Comparison of Two Thulium Optical Clocks
A. Golovizin, D. Mishin, D. Provorchenko +2
The experimental comparison of two thulium optical lattice clocks in a time interval of up to one hour has been carried out. The synchronous comparison of a clock transition in two…
Combined microwave and optical spectroscopy for hyperfine structure analysis in thulium atoms
Denis Mishin, Dmitry Tregubov, Nikolay Kolachevsky +1
The hyperfine structure of atoms and ions is widely used in fundamental and applied research. Accurate knowledge of hyperfine splitting values is essential for quantum metrology ap…
Efficient loading of thulium atoms in a compact MOT for a transportable optical clock
A. Golovizin, D. Tregubov, D. Mishin +2
We report on building of a compact vacuum chamber for spectroscopy of ultracold thulium and trapping of up to 13 million atoms. Compactness is achieved by obviating a classical Zee…
Extraordinary low systematic frequency shifts in bi-colour thulium optical clock
A. Golovizin, D. Tregubov, E. Fedorova +5
Optical atomic clocks have already overcome the eighteenth decimal digit of instability and uncertainty demonstrating incredible control over external perturbations of the clock tr…
Simultaneous two initial clock states preparation for thulium optical clock
E. Fedorova, A. Golovizin, D. Tregubov +5
Due to the low sensitivity of the thulium optical clock to black-body radiation and good accuracy and stability estimations, it appears to be one of the most promising transportabl…
