On anisotropy of the pressure tensor and the force density for a polarizable fluid in an electromagnetic field

L.G. Suttorp and S.R. De Groot

Physica A: Statistical Mechanics and its Applications, 1981, vol. 108, issue 2, 361-370

Abstract: By means of a statistical derivation it is shown that the momentum-balance equation of a polarized fluid contains a force term that is the divergence of an anisotropic tensor (frsol|1/5)PP + (110)P2U, where P is the polarization. However, for a fluid in equilibrium this force term is compensated by an anisotropic part in the pressure tensor. The same is true for a fluid in an optical field if time-averaged quantities are considered.
