We demonstrate optical levitation of SiO 2 spheres with masses ranging from 0.1 to 30 ng. In
high vacuum, we observe that the measured acceleration sensitivity improves for larger …

Abstract The Casimir‐Lifshitz force, FC− L, has become a subject of great interest to both
theoretical and applied physics communities due to its fundamental properties and potential …

Complex interaction geometries offer a unique opportunity to modify the strength and sign of
the Casimir force. However, measurements have traditionally been limited to sphere-plate or …

In soft condensed matter physics, effective interactions often emerge due to the spatial
confinement of fluctuating fields. For instance, microscopic particles dissolved in a binary …

We show that the optical trap** and manipulation of spherical-shaped semiconductor
(germanium) particles can be strongly modulated and controlled using optical tweezers …

We calculate the Casimir force and its gradient between a spherical and a planar gold
surface. Significant numerical improvements allow us to extend the range of accessible …

The superposition of a Gaussian mode and a Laguerre-Gauss mode with ℓ= 0, p≠ 0
generates the so-called bottle beam: a dark focus surrounded by a bright region. In this …

Rapid advances in Biophotonics are revolutionizing the illumination of several diseases
and, among them, the monitoring of cancer pathogenesis and therapy. Today, several efforts …

A technique to levitate and measure the three-dimensional position of micrometer-sized
dielectric spheres with heterodyne detection is presented. The two radial degrees of …

Observation at the single molecule level has been a revolutionary tool for molecular
biophysics and materials science, but single molecule studies of solution-phase chemistry …
