Akimov as part o f Quantum Optics and Related Topics\n\n\nAbstract\nBose-Einstein condensat ion (BEC) is a powerful tool for a wide range of research activities\, a l arge fraction of which is related to quantum simulations. Various problems may benefit from different atomic species. Thulium atoms possess dipole m oment of 4 Bohr magneton in the ground state\, allowing long-term interact ions. It also has number of non-chaotic low-field Feshbach resonances\, al lowing fine control of the near-filed interactions. It also has relatively simple level structure compared to the other magnetic lanthanoids and thu s is a quite promising subject for applications in quantum simulations.\nN evertheless\, cooling down novel species interesting for quantum simulatio ns to BEC temperatures requires a substantial amount of optimization and i s usually considered to be a difficult experimental task. Here we report o n implementation of the Bayesian machine learning technique to optimize th e evaporative cooling of thulium atoms and achieved BEC in an optical dipo le trap. Two dipole traps were used: 532 nm light and 1064 nm light\, in b oth the condensation was achieved. We also analyzed the atomic loss mechan ism for the 532 nm optical trap\, used in the Bose-condensation experiment \, and compares it with the alternative and more traditional micron-range optical dipole trap.\nWhile the condensate of the thulium atom has a lot o f applications in quantum simulations and other areas of physics\, it can also serve as a unique diagnostic tool for many atomic experiments. In the present study\, the Bose-Einstein condensate of the thulium atom was succ essfully utilized to diagnose an optical lattice and detect unwanted refle ctions in the experiments with the 1064 nm optical lattice\, which will fu rther be used in a quantum gas microscope experiment.\nThis work was suppo rted by Rosatom in the framework of the Roadmap for Quantum computing (Con tract No. 868-1.3-15/15-2021 dated October 5\, 2021).\n LOCATION:https://researchseminars.org/talk/QOART/3/ END:VEVENT END:VCALENDAR
