We argue that sets of correlations corresponding to information-theoretic principles, or more generally to consistent physical theories, must be closed under a natural set of operations. Hence, st...

Rev. A 79, 027801 (2009)], our position that the calculation of dispersion forces should be based preferably on the Lorentz force (or, equivalently, on Maxwell's stress tensor) is put into question, and it is argued that one should resort to Minkowski's stress tensor inste...
