Quadrupole anisotropy from photon quantum effects

Alexei V. Nesteruk, Roy Maartens

Research output: Contribution to journalArticlepeer-review


We consider quantum effects of an electromagnetic field in a radiation-dominated almost frw spacetime. The dominant non-local quantum correction to the photon distribution is a quadrupole moment, corresponding to an effective anisotropic pressure in the energy-momentum tensor.
