There are two different proposals for the momentum of light in a transparent dielectric of refractive index n: Minkowski's version nE/c and Abraham's version E/(nc), where E and c are the energy and vacuum speed of light, respectively. Despite many tests and debates over nearly a century, momentum of light in a transparent dielectric remains controversial. In this Letter, we report a direct observation of the inward push force on the free end face of a nanometer silica filament exerted by the…

Theoretical analysis of the force on the end face of a nanofilament exerted by an outgoing light pulse
The slight deformations observed upon transmission of a light pulse through a short length of a silica glass nano-filament offer the possibility of determining the momentum of light inside the…
What is wrong with the interpretation of recent nano-filament experiments?
In a recent paper, W. She, J. Yu and R. Feng reported the slight deformations observed upon transmission of a light pulse through a short length of a silica glass nano-filament. Relating the shape…
Comment on "Observation of a push force on the end face of a nanometer silica filament exerted by outgoing light".
TLDR
A brief discussion is given on the recent experiment of She et al. in relation to the Abraham-Minkowski energy-momentum problem.
Nanomechanical effects of light unveil photons momentum in medium
TLDR
This work quantitatively and cleanly measure nanomehanical dynamics of water surface excited by radiation pressure of a laser beam and uses two independent pump-probe techniques to validate a nano- bump on the water surface in quantitative agreement with the Minkowski’s momentum of light.
Photon energy dependence of the light pressure exerted onto a thin silicon slab
We review the theory of ponderomotive forces of classical nonionizing electromagnetic (EM) radiation exerted on dispersive matter. Minkowski's EM energy and momentum density lack any dispersion term…

TLDR
It is explained why two distinct momenta are needed to describe light in a medium and why each appears as the natural, and experimentally observed, momentum in appropriate situations.
Optically induced force in a curve waveguide
We show that optically induced force (OIF) that arises in a curve waveguide due to a change of the momentum of light wave because of a change of its direction is not a special kind of OIF. A…
Experimental evidence for Abraham pressure of light
The question of how much momentum light carries in media has been debated for over a century. Two rivalling theories, one from 1908 by Hermann Minkowski and the other from 1909 by Max Abraham,…
Self-alignment and instability of waveguides induced by optical forces
We introduce a fundamental property of waveguides induced by the forces of the guided light, namely, the ability to self-align or be in instability. A nanoscale waveguide broken by an offset and a…
Negative radiation pressure and negative effective refractive index via dielectric birefringence.
TLDR
It is shown that light guided in a planar dielectric slab geometry incorporating a biaxial medium has lossless modes with group and phase velocities in opposite directions, which represents a new geometry for achieving negative radiation pressure in a wide range of frequencies with minimal loss.
