The center-of-mass motion of optically trapped dielectric nanoparticles in a vacuum is
extremely well decoupled from its environment, making a powerful tool for measurements of …

We study the Casimir interaction between two dielectric spheres immersed in a salted
solution at distances larger than the Debye screening length. The long distance behavior is …

Reflection and refraction of light can be used to trap small dielectric particles in the
geometrical optics regime. Absorption of light is usually neglected in theoretical calculations …

Oscillators based on levitated particles are promising for the development of ultrasensitive
force detectors. The theoretical performance of levitated nanomechanical sensors is usually …

We propose and evaluate a new type of optical force microscope based on a standing-wave
optical trap. Our microscope, calibrated in situ and operating in a dynamic mode, is able to …

One of the most intriguing manifestations of quantum zero-point fluctuations are the van der
Waals and Casimir forces, often associated with vacuum fluctuations of the electromagnetic …
