BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

Optomechanics, the study of the mechanical interaction of light with matter, has proven to be
a fruitful area of research that has yielded many notable achievements, including the direct …

We present experimental results on optical trapping of Yb-doped β-NaYF subwavelength-
thickness high-aspect-ratio hexagonal prisms with a micron-scale radius. The prisms are …

Optical levitation of dielectric particles in vacuum is a powerful technique for precision
measurements, testing fundamental physics, and quantum information science …

To control and enhance light–matter interactions at the nanoscale, two parameters are
central: the spectral overlap between an optical cavity mode and the material's spectral …

The nanomechanical resonator based on a levitated particle exhibits unique advantages in
the development of ultrasensitive electric field detectors. We demonstrate a three …

We implement an all-electrical controller for 3D feedback cooling of an optically levitated
nanoparticle capable of reaching subkelvin temperatures for the center-of-mass motion. The …

We experimentally demonstrate stable trapping and controlled manipulation of silica
microspheres in a structured optical beam consisting of a dark focus surrounded by light in …

We present a hybrid trapping platform that allows us to levitate a charged nanoparticle in
high vacuum using either optical fields, radio-frequency fields, or a combination thereof. Our …

Here we present and demonstrate a non-contact optical measuring method for the
characterization of both the shape and size parameters of nanoparticles using optical …
