“…In recent years, with the development of microstructural deformation measurement technology, together with numerical simulations, some scholars have measured the gas-liquid interface deformation caused by light pressure at the nanoscale and carried out numerical simulation based on theoretical models. The results are in good agreement with Minkowski momentum [10][11][12][13]. However, similar experiments conducted by Zhang and She et al after changing the experimental parameters showed the sunken of the gas-liquid interface caused by light pressure, thus supporting the Abraham momentum [14].…”

This paper reviews the history and origin of the Abraham-Minkowski controversy and points out that it is a continuation of the controversy over the speed of light in medium. Upon considering an aircraft flying at a constant speed along the great-circle route from the perspective of a geosynchronous space station, we show that the A-M controversy arises from non-local observation. The relative motion refractive index and the gravitational field refractive index are defined by the space-time metric tensor, which reveals the A-M controversy hidden in special and general relativity. As another example, we take light propagating over the surface of the sun, and show that Minkowski and Abraham forces are responsible for the gravitational deflection of light and the Shapiro time delay, respectively. Overall, we heuristically conclude that non-local observation is the cause of the A-M controversy.

“…The canonical (Minkowski) momentum is related to the idea of translations within, or relative to, a host medium and to the wavelength of light, explaining the immersed mirror experiment and wavelike phenomena such as diffraction. However, interpreting the manifestations of photon momentum transfer remains problematic [7,[11][12][13][14][15][16][17].…”

Photon momentum transfer at water/air interfaces under total internal reflection

The transfer of photon momentum at the water/air interface is important for optical manipulation of minute particles and is at the heart of the Minkowski-Abraham controversy. We use photoacoustic (PA) detection of ultrasound waves generated when pulsed laser light meets the water/air interface at 3.9°C (zero thermal expansion), to distinguish momentum transfer from thermoelastic effects. The PA waves dependence on the angle of incidence reveals that momentum transfer maximizes at the critical angle. Momentum transfer is most efficient when the photons travel in water and remain in water after total reflection at the interface, rather than when they cross the interface between dielectric media.

“…[35,39] The fringe pattern was self-calibrating for nanoscale measurements and has been used as a direct measurement of laser-induced deformation of the AW interface. [35,40,41] To measure the spatial profile of the AW interface, keeping the pump beam fixed, we scanned the probe beam across the AW interface by translating the mirror M3 (Figure 1a).…”

Manipulating micro/nanoparticles on deformed liquid interfaces induced by radiation pressure presents an active, non‐invasive, and contactless method. However, a significant challenge arises due to the relatively small magnitude of the radiation force in normal incidence. Nevertheless, this technique holds immense utility in controlling particle movement at interfaces, with numerous applications in both physical and biological contexts. To overcome this, the peculiar properties of total internal reflection (TIR) in retro‐reflection mode are expoited to create a high amplitude bulge on the water surface, which can migrate radius particles as forcibly as the traditional micro‐post paradigm. The bulge height is measured using an interferometric technique, and the underlying physics are demonstrated using an imitated particle with a capillary charge. By shining two pump lasers, an interface shape is created with increasing complexity, and the relative pump laser intensity is tuned to migrate particles in the desired direction. The method provides a non‐invasive and contactless way to remotely actuate almost all types of micro/nanoparticles at the liquid surface.
