Coherence of Microwave and Optical Qubit Levels in Neutral Thulium
Denis Mishin, Dmitry Tregubov, Nikolay Kolachevsky +1
Hyperfine-encoded qubits in alkali atoms have established themselves as robust platforms for quantum computing, while alkaline-earth-like elements expand the state manipulation too…
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…
Deep Laser Cooling of Thulium Atoms to Sub-K Temperatures in Magneto-Optical Trap
Daniil Provorchenko, Dmitry Tregubov, Denis Mishin +6
Deep laser cooling of atoms, ions, and molecules facilitates the study of fundamental physics as well as applied research. In this work, we report on the narrow-line laser cooling…
Measurement of the == transition in Muonium
G. Janka, B. Ohayon, I. Cortinovis +9
Muons are puzzling physicists since their discovery when they were first thought to be the meson predicted by Yukawa to mediate the strong force. The recent results at Fermilab on…
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…
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…
Two-temperature momentum distribution in a Thulium magneto-optical trap
E. Kalganova, O. Prudnikov, A. Golovizin +6
Second-stage laser cooling of thulium atoms at the 530.7 nm transition with a natural linewidth of 350 kHz offers an interesting possibility to study different regimes of a magneto…
Inner-shell magnetic dipole transition in Tm atom as a candidate for optical lattice clocks
D. Sukachev, S. Fedorov, I. Tolstikhina +7
We consider a narrow magneto-dipole transition in the Tm atom at the wavelength of m as a candidate for a 2D optical lattice clock. Calculating dynamic polarizabil…
Measurement of the 5D Level Polarizabilty in Laser Cooled Rb atoms
S. Snigirev, A. Golovizin, D. Tregubov +5
We report on accurate measurements of the scalar and tensor polarizabilities of the 5D fine structure levels 5D3/2 and 5D5/2 in Rb. The measured values show reasonable corresponden…
