Leonhardt's insight inspired Barnett's 2010 resolution published in an Editors' Suggestion of Physical Review Letters, which is one of the most highly cited papers in the Abraham–Minkowski controversy. In Barnett's resolution, the Abraham version is the kinetic momentum and the Minkowski version is the canonical momentum; "the kinetic momentum of a body is simply the product of its mass and velocity", while "the canonical momentum of a body is simply Planck's constant divided by its de Broglie wavelength". Barnett argues that the medium Einstein-box thought experiment (also known as "Balazs thought experiment") supports Abraham momentum while the photon–atom Doppler resonance absorption experiment supports Minkowski momentum. In other words, the photon takes Abraham momentum in the Einstein's box thought experiment, while it takes Minkowski momentum in the photon–atom Doppler resonance absorption experiment; with both Abraham and Minkowski momenta being correct photon momenta. However Wang disagrees, criticizing that Barnett's physical model "is not consistent with global momentum-energy conservation law in the principle-of-relativity frame". "In Barnett's theory, the argument for supporting Abraham momentum is based on the analysis of the Einstein-box thought experiment by the 'center-of-mass-energy' approach, where the global momentum-energy conservation law is employed to obtain Abraham photon momentum and energy in the medium box in the laboratory frame. At first sight, such an approach is indeed impeccable; however, upon more careful investigation, one may find that the approach itself has implicitly assumed the Abraham momentum to be the correct momentum; thus leaving readers an open question: Do the Abraham momentum and energy obtained still satisfy the global momentum-energy conservation law in all inertial frames of reference so that the argument is consistent with the principle of relativity?"
