Zero-Point Momentum in Complex Media
In this work we apply field regularization techniques to formulate a number of new phenomena related to momentum induced by electromagnetic zero-point fluctuations. We discuss the zero-point momentum associated with magneto-electric media, with moving media, and with magneto-chiral media.

متن کاملOptical momentum and angular momentum in complex media: from the Abraham–Minkowski debate to unusual properties of surface plasmon-polaritons
Weexamine themomentum and angularmomentum (AM) properties ofmonochromatic optical fields in dispersive and inhomogeneous isotropicmedia, using the AbrahamandMinkowski-type approaches, as well as the kinetic (Poynting-like) and canonical (with separate spin and orbital degrees of freedom) pictures.While the kinetic Abraham–Poyntingmomentumdescribes the energy flux and the group velocity of thewa...
متن کاملThermal self-energies at zero momentum.
In general the zero momentum limit of thermal self-energies calculated in perturbation theory depends on the order in which the time and the space components of the momentum are taken to zero. We show that this is an artifact of the perturbative calculation, and in fact the non-analyticity of the one-loop self-energy disappears when it is calculated with improved vertices and/or improved propag...
متن کاملPhoton recoil momentum in dispersive media.
A systematic shift of the photon recoil momentum due to the index of refraction of a dilute gas of atoms has been observed. The recoil frequency was determined with a two-pulse light grating interferometer using near-resonant laser light. The results show that the recoil momentum of atoms caused by the absorption of a photon is n variant Planck's k, where n is the index of refraction of the gas...
متن کاملElectromagnetic energy-momentum tensors in media
It is pointed out that the previous energy-momentum tensors of Minkowski and Abraham for the electromagnetic field in continuous media are based on a covariant formulation which does not reflect a symmetry inherent to the system. Instead, taking into account the intrinsic invariance under Lorentz transformations involving the reduced speed of light in such a medium, a compact and fully consiste...
