چکیده
Particle production by expanding in the future light cone scalar quantum field is studied assuming that initial state associated with quasiequilibrium statistical operator corresponding to fluid dynamics. We calculate particle from a longitudinally boost-invariant designed as simple but reliable model for central rapidity region of relativistic collision. Exact diagonalization performed introducing notion quasiparticles.

Cosmological Particle Creation and Dynamical Casimir Effect
In this paper we have considered the particle creation in the spatially closed Robertson-Walker space-time. We considered a real massive scalar field which con-formally coupled to the Robertson-Walker background. With the dependence of the scale factor on time, the case under consideration is a dynamical Casimir effect with moving boundaries.
متن کاملCosmological consequences of particle creation during inflation
Particle creation during inflation is considered. It could be important for species whose interaction is of gravitational strength or weaker. A complete but economical formalism is given for spin-zero and spin-half particles, and the particle abundance is estimated on the assumption that the particle mass in the early universe is of order the Hubble parameter H. It is roughly the same for both ...
متن کاملPrimordial hadrosynthesis in the Little Bang
The present status of soft hadron production in high energy heavy-ion collisions is summarized. In spite of strong evidence for extensive dynamical evolution and collective expansion of the fireball before freeze-out I argue that its chemical composition is hardly changed by hadronic final state interactions. The measured hadron yields thus reflect the primordial conditions at hadronization. Th...
متن کاملAnalogue of cosmological particle creation in an ion trap.
We study phonons in a dynamical chain of ions confined by a trap with a time-dependent (axial) potential strength and demonstrate that they behave in the same way as quantum fields in an expanding or contracting Universe. Based on this analogy, we present a scheme for the detection of the analogue of cosmological particle creation which should be feasible with present day technology. In order t...

evolution. We conclude that, unfortunately, the spectrum is very tilted, with spectral index ns = 3. The amplitude of fluctuations at horizon crossing is given by < (δρ/ρ) >∼ (R0/d)2S−1 E k, where SE 1 is the Euclidean action of the instanton describing the nucleation of a bubble and k is the wavenumber in units of the curvature scale. The spectrum peaks on the smallest possible relevant scale,...
