Infrared and optical spectroscopy represents one of the most informative methods in
advanced materials research. As an important branch of modern optical techniques that has …

Since their invention just over 20 years ago, optical traps have emerged as a powerful tool
with broad-reaching applications in biology and physics. Capabilities have evolved from …

Optical manipulations utilizing the mechanical effect of light have been indispensable in
various disciplines. Among those various manipulations, optical pulling has emerged …

The light-matter interaction has been at the heart of major advances from the atomic scale
right to the microscopic scale over the past four decades. Confinement by light, embodied by …

We present a study of the optical force on a small particle with both electric and magnetic
response, immersed in an arbitrary non-absorbing medium, due to a generic incident …

We establish the time-averaged total force on a subwavelength-sized particle in a time-
harmonic-varying field. Our analysis is not restricted to the spatial dependence of the …

Light forces on small (Rayleigh) particles are usually described as the sum of two terms: the
dipolar or gradient force and the scattering or radiation pressure force. The scattering force …

Microwires and nanowires have been manufactured by using a wide range of bottom-up
techniques such as chemical or physical vapor deposition and top-down processes such as …

We report the first experimental observation of momentum transfer from a surface plasmon to
a single dielectric sphere. Using a photonic force microscope, we measure the plasmon …

A detailed study of time-averaged electromagnetic forces on subwavelength-sized particles
is presented. An analytical decomposition of the force into gradient and scattering-plus …
