Absence of particle creation in a hot Friedmann universe

Journal Article Linde, A D - JETP Lett. (Engl. Transl.); (United States)

It is shown that taking into account the temperature dependence of particle masses in an expanding Friedmann universe leads to nearly complete suppression of the creation of particles with masses m< or approx. =10/sup 17/ GeV.
Effects of temperature on the creation of particles in a hot Friedmann universe

Journal Article Guenther, U ; Zhuk, A I - Astrophysics (Engl. Transl.); (United States)

The creation of particles (bosons and fermions) in a hot Friedmann universe from an initial state described by a thermal density matrix is considered in the case when the effective mass of the particles depends on the temperature. It is shown that for scalar particles allowance for the temperature effects leads to a very strong suppression of the creation process. For spinor particles, allowance for the temperature effects leads to a strong suppression of the process of creation from an initial vacuum state. However if the creation of the spinor particles takes place from a state described by a thermalmore »« less
Charged particle creation in the steady state universe

Journal Article Liboff, R L - Astrophysical Journal; (United States)

The birth of a particle of charge q(0), initial mass m(0), and radius a in the steady state universe is studied. With the particle's birth, in accord with causality, gravity, and Coulomb fields propagate away from it with the speed of light. Field energies are supplied by the particle's mass which subsequently decays in time. Asymptotic solution to a nonlinear equation for the remaining mass gives the criterion m(0) is greater that q(0){sup 2}/2ac{sup 2} as a necessary condition for the initial mass to survive the field expansion. The resulting radius of a classical charged particle is found to bemore »« less

Gravitational particle creation in a stiff matter dominated universe

Journal Article Lankinen, Juho ; Vilja, Iiro - Journal of Cosmology and Astroparticle Physics

A scenario for gravitational particle creation in a stiff matter dominated flat Friedmann-Robertson-Walker universe is presented. The primary creation of scalar particles is calculated using quantum field theory in curved spacetime and it is found to be strongly dependent on the scalar mass and the expansion parameter of the universe. The particle creation is most effective for a very massive scalar field and large expansion parameter. We demonstrate the phenomenon by applying it to cosmological toy model scenario, where secondary particles are created by the scalar field decay.
