The workshop Quantum sensing and fundamental physics with levitated mechanical systems aims at bringing together theorists and experimentalists working in the field of levitated nano/micromechanical systems, using various platforms (optical, electrical, magnetic) and in related fields in order to discuss the most recent results and exchange ideas in order to explore new opportunities in quantum sensing and fundamental physics. In particular, the workshop will cover the following topics: levitated optomechanics, levitated magnetomechanics, levitated micro and nanosensors, hybrid quantum systems, spin-mechanics, search for dark matter or modified gravity or new physics beyond the standard model, fundamental science in space.
