“…The recent burst of theoretical and experimental [54][55][56] publications indicates both an abiding interest in the problem and, apparently, a lack of consensus or certainty about what the correct answer is. The traditional arguments can be found in reviews like Refs.…”

By restating geometrical optics within the field-theoretical approach, the classical concept of a photon (and, more generally, any elementary excitation) in arbitrary dispersive medium is introduced, and photon properties are calculated unambiguously. In particular, the canonical and kinetic momenta carried by a photon, as well as the two corresponding energy-momentum tensors of a wave, are derived from first principles of Lagrangian mechanics. As an example application of this formalism, the Abraham-Minkowski controversy pertaining to the definitions of these quantities is resolved for linear waves of arbitrary nature, and corrections to the traditional formulas for the photon kinetic energy-momentum are found. Several other applications of axiomatic geometrical optics to electromagnetic waves are also presented.

“…In a transparent dielectric of refractive index n, Minkowski suggested for the momentum of light [3], whereas Abraham suggested for the same physical quantity [4], where c nE / ) /(nc E E and c are the energy and vacuum speed of light respectively. There are a significant number of irradiative theories to clarify these two momenta [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], the number of experimental tests are, however, far less [23][24][25][26]. One of the experimental tests observing the radiation pressure at the water-air interface [23] is now reckoned to support Abraham momentum [2].…”

Observation of a Push Force on the End Face of a Nanometer Silica Filament Exerted by Outgoing Light

There are two different proposals for the momentum of light in a transparent dielectric of refractive index n: Minkowski's version and Abrahm's version , where c nE / ) /(nc E 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 end face of a free nm fiber taper exerted by the outgoing light. Our results clearly support Abraham momentum. Our experiment also indicates an inward surface pressure on a dielectric exerted by the incident light, different from the commonly recognized pressure due to the specular reflection. Such an inward surface pressure by the incident light may be useful for precise design of the laser-induced inertially-confined fusion.

“…Here, t int = L/v g denotes the interaction time with L as the cell length (≅50 mm here), v g the optical group velocity and p = nhk the photon momentum 15 , for which we take the free space value since the refractive index n here is very close to unity. We arrive at an expected deflection angle…”
