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."}],"author":[{"id":"09501ff6-dca7-11ea-a8ae-b3e0b9166e80","orcid":"0000-0003-0582-2946","last_name":"Agafonova","full_name":"Agafonova, Sofya","first_name":"Sofya"},{"id":"4328fa4c-f128-11eb-9611-c107b0fe4d51","first_name":"Umang","last_name":"Mishra","full_name":"Mishra, Umang"},{"id":"2E054C4C-F248-11E8-B48F-1D18A9856A87","last_name":"Diorico","full_name":"Diorico, Fritz R","orcid":"0000-0002-4947-8924","first_name":"Fritz R"},{"id":"4C02D85E-F248-11E8-B48F-1D18A9856A87","first_name":"Onur","last_name":"Hosten","full_name":"Hosten, Onur","orcid":"0000-0002-2031-204X"}],"citation":{"apa":"Agafonova, S., Mishra, U., Diorico, F.
