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…
