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…
Random to chaotic temperature transition in low-field Fano-Feshbach resonances of cold thulium atoms
V. A. Khlebnikov, D. A. Pershin, V. V. Tsyganok +5
Here, we report on the observation of a random to chaotic temperature transition in the spacing of Fano-Feshbach resonances in the ultracold polarized gas of thulium atoms. This tr…
Inner-shell clock transition in atomic thulium with small BBR shift
A. Golovisin, E. Fedorova, D. Tregubov +4
With direct polarizability measurements we demonstrated extremely low sensitivity of the inner-shell clock transition at m in Tm atoms to external dc electric fields and b…
