Abstract

Optomechanical systems have come to the fore in the last two decades. This field focuses upon the interaction of light with matter. It can lead to new approaches for precision measurement and the study of quantum physics. Light may both probe the system and mediate a reduction in energy of the system (cooling). In this domain, levitated optomechanics has emerged as an important direction which holds a mesoscopic particle in isolation from its surroundings. This reduces dissipation. This may be performed using optical trapping, though levitation through electrostatic or other means offer interesting alternative. Exploiting the rotational degree of freedom by spinning the trapped particle adds further value. By drawing on some of the key international work, including that from my group, I will review some of particular advances made in such rotational levitated optomechanics using birefringent particles.
