Screening of magnetic fields by charged Bose condensate
Alexander D. Dolgov, Angela Lepidi
The space-space component of the photon polarization operator is calculated in zero frequency limit for a medium with Bose-Einstein condensate (BEC) of electrically charged particl…
General treatment of isocurvature perturbations and non-Gaussianities
David Langlois, Angela Lepidi
We present a general formalism that provides a systematic computation of the linear and non-linear perturbations for an arbitrary number of cosmological fluids in the early Univers…
Ferromagnetic properties of charged vector boson condensate
Alexander D. Dolgov, Angela Lepidi, Gabriella Piccinelli
Bose-Einstein condensation of W bosons in the early universe is studied. It is shown that, in the broken phase of the standard electroweak theory, condensed W bosons form a ferroma…
Electrostatic interaction in plasma with charged Bose condensate
Angela Lepidi
Screening in plasma with Bose-Einstein condensate is studied. Finite temperature effects are taken into account. It is shown that, due to condensate effects, the potential has seve…
Screening effects in plasma with charged Bose condensate
Alexander D. Dolgov, Angela Lepidi, Gabriella Piccinelli
Screening of Coulomb field of test charge in plasma with Bose condensate of electrically charged scalar field is considered. It is found that the screened potential contains severa…
Electrodynamics at non-zero temperature, chemical potential, and Bose condensate
Alexander D. Dolgov, Angela Lepidi, Gabriella Piccinelli
Electrodynamics of charged scalar bosons and spin 1/2 fermions is studied at non-zero temperature, chemical potentials, and possible Bose condensate of the charged scalars. Debye s…
