The key ingredient is a light-shift manipulation that creates spatially varying cooling parameters, enabling efficient capture and accumulation of atoms within a cavity mode. Demonstrated with rubidium atoms, a continuous flux from a source cell is funneled through the magneto-optical trap into the cavity mode, where the atoms are cooled and maintained below 10µK in steady state without time-sequenced operation.

Torsional oscillators present an opportunity in this regard due to their remarked isolation from environmental noise. For torsional motion, an effective employment of optical cavities to enhance optomechanical interactions—as already established for linear oscillators—so far faced certain challenges. Here, we propose a concept for sensing and manipulating torsional motion, where exclusively the torsional rotations of a pendulum are mapped onto the path length of a single two-mirror optical cavity. The concept inherently alleviates many limitations of previous approaches. A proof-of-principle experiment is conducted with a rigidly controlled pendulum to explore the sensing aspects of the concept and to identify practical limitations in a potential state-of-the art setup. Based on this study, we anticipate development of precision torque sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz, while the motion of the pendulums are dominated by quantum radiation pressure noise at sub-microwatts of incoming laser power. These developments will provide horizons for experiments at the interface of quantum mechanics and gravity.","lang":"eng"}],"title":"Zigzag optical cavity for sensing and controlling torsional motion","author":[{"id":"09501ff6-dca7-11ea-a8ae-b3e0b9166e80","first_name":"Sofya","orcid":"0000-0003-0582-2946","full_name":"Agafonova, Sofya","last_name":"Agafonova"},{"last_name":"Mishra","full_name":"Mishra, Umang","id":"4328fa4c-f128-11eb-9611-c107b0fe4d51","first_name":"Umang"},{"id":"2E054C4C-F248-11E8-B48F-1D18A9856A87","first_name":"Fritz R","orcid":"0000-0002-4947-8924","full_name":"Diorico, Fritz R","last_name":"Diorico"},{"orcid":"0000-0002-2031-204X","full_name":"Hosten, Onur","last_name":"Hosten","first_name":"Onur","id":"4C02D85E-F248-11E8-B48F-1D18A9856A87"}],"acknowledgement":"We thank Pere Rosselló for his contributions to the initial modeling of the presented sensing technique.

While the project remains ongoing, significant progress has been\r\nmade.\r\nA key contribution of this work is the development of Quantrol, an experimental control\r\nsystem leveraging the ARTIQ framework. This software enables precise timing and control\r\nwithout requiring prior knowledge of ARTIQ’s implementation details or coding experience.\r\nThe interface offers user friendly visual comprehension of the experimental sequence and\r\nextended capabilities, allowing researchers to scan variables with a simple click of a mouse.\r\nThe main proposed project is to implement atom interferometric sequence with squeezed input\r\nstates inside of a dipole trap generated by a high finesse cavity. The presence of the dipole\r\ntrap allows one dimensional atomic cloud split while maintaining relatively strong confinement\r\nin other directions.\r\nWe are currently able to trap and cool 87Rb atoms to few micro kelvin temperatures, load\r\nthem into the dipole trap and state prepare them to be used for squeezing and interferometric\r\nsequence.","lang":"eng"}],"title":"Towards a quantum entanglement enhanced atom interferomter","has_accepted_license":"1","file_date_updated":"2024-07-11T10:26:22Z","file":[{"success":1,"relation":"main_file","creator":"vli","date_created":"2024-07-11T10:26:22Z","file_name":"PhD_Thesis_Vyacheslav_Li_no_signatures_PDFA.pdf","file_size":6729761,"file_id":"17228","checksum":"15b2dbe8d2c9ed7ca5dd413827928077","access_level":"open_access","content_type":"application/pdf","date_updated":"2024-07-11T10:26:22Z"},{"content_type":"application/x-zip-compressed","date_updated":"2024-07-11T10:26:22Z","creator":"vli","relation":"source_file","access_level":"closed","file_id":"17229","checksum":"16e904a11d8d0ebb167cb654ddfc7fe5","file_size":9542859,"file_name":"PhD Thesis Vyacheslav Li.zip","date_created":"2024-07-11T10:26:22Z"}],"alternative_title":["ISTA Thesis"],"type":"dissertation","degree_awarded":"PhD","date_updated":"2026-07-08T08:50:57Z","ddc":["530"],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_created":"2024-07-11T09:46:48Z","month":"07","oa":1,"oa_version":"Published Version","publication_status":"published","year":"2024","related_material":{"record":[{"id":"11438","status":"public","relation":"part_of_dissertation"}]},"day":"11","date_published":"2024-07-11T00:00:00Z","_id":"17225","project":[{"name":"A quantum hybrid of atoms and milligram-scale pendulums: towards gravitational quantum mechanics","_id":"bdb2a702-d553-11ed-ba76-f12e3e5a3bc6","grant_number":"101087907"}],"license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","page":"79","language":[{"iso":"eng"}],"status":"public","article_processing_charge":"No","department":[{"_id":"GradSch"},{"_id":"OnHo"}]}]
