Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not
exist for their centre-of-mass motion. By levitating nanoparticles in ultra-high vacuum …

The momentum carried by structured light fields exhibits a rich array of surprising features. In
this work, we generate transverse orbital angular momentum (TOAM) in the interference field …

Control of the potential energy and free evolution lie at the heart of levitodynamics as key
requirements for sensing, wave function expansion, and mechanical squeezing protocols …

Levitated Nanoparticles have received much attention for their potential to perform quantum
mechanical experiments even at room temperature. However, even in the regime where the …

A circularly polarized laser beam is used to levitate and control the rotation of microspheres
in high vacuum. At low pressure, rotation frequencies as high as 6 MHz are observed for …

Manipulating the rotational as well as the translational degrees of freedom of rigid bodies
has been a crucial ingredient in diverse areas, from optically controlled micro-robots …

The fastest-spinning man-made object is a tiny dumbbell rotating at 5 GHz. The smallest
wind-up motor is constructed from a DNA molecule. Picoliter volumes of fluids are remotely …

We show how charged levitated nano-and micro-particles can be cooled by interfacing them
with an RLC circuit. All-electrical levitation and cooling is applicable to a wide range of …
