The Hubble Effective Potential
نویسندگان
چکیده
We generalize the effective potential to scalar field configurations which are proportional to the Hubble parameter of a homogeneous and isotropic background geometry. This may be useful in situations for which curvature effects are significant. We evaluate the one loop contribution to the Hubble Effective Potential for a massless scalar with arbitrary conformal and quartic couplings, on a background for which the deceleration parameter is constant. Among other things, we find that inflationary particle production leads to symmetry restoration at late times.

Hubble-bubble in Iranian Folklore
Hubble-bubble has been the most common device for smoking tobacco in Iran and its neighboring. It has a folkloric name in every region. Hubble-bubble consists of a glass pitcher or pottery at the bottom, a wooden body in the middle, a wooden or plastic tube attached to the body for puffing, and a censer at the top to put tobacco and charcoal. Puffing causes the charcoal to catch fire and the to...

متن کاملRadiative Lifting of Flat Directions of the MSSM in de Sitter Background
The one-loop effective potential for a charged scalar field in de Sitter background is studied. We derive an approximate form for the gauge boson propagator with a general covariant gauge-fixing parameter ξ. This expression is used to derive an explicitly gauge-invariant effective potential, which agrees with earlier results obtained in Landau gauge. Adding the scalarand fermion-loop contributi...
