Quantum cosmology with dynamical vacuum in a minimal-length scenario
نویسندگان
چکیده
In this work, we consider effects of the dynamical vacuum in quantum cosmology presence a minimum length introduced by GUP (generalized uncertainty principle) related to modified commutation relation $[\hat{X},\hat{P}] := \frac{i\hbar}{ 1 - \beta\hat{P}^2 }$ . We determine wave function Universe $ \psi_{qp}(\xi,t)$, which is solution Wheeler-DeWitt equation representation quasi-position space, limit where scale factor small. Although $\psi_{qp}(\xi,t)$ physically acceptable state it not realizable because \psi_{qp}(\xi,t)$ has infinite norm, as ordinary case with no minimal length.

Quantum cosmology with a minimal length
Quantum cosmology in the presence of a fundamental minimal length is analyzed in the context of the flat isotropic and the Taub cosmological models. Such minimal scale comes out from a generalized uncertainty principle and the quantization is performed in the minisuperspace representation. Both the quantum Universes are singularity-free and (i) in the isotropic model no evidences for a Big-Boun...
متن کاملCosmology with minimal length uncertainty relations
We study the effects of the existence of a minimal observable length in the phase space of classical and quantum de Sitter (dS) and Anti de Sitter (AdS) cosmology. Since this length has been suggested in quantum gravity and string theory, its effects in the early universe might be expected. Adopting the existence of such a minimum length results in the Generalized Uncertainty Principle (GUP), w...
متن کاملQuantum vacuum noise in physics and cosmology.
The concept of the vacuum in quantum field theory is a subtle one. Vacuum states have a rich and complex set of properties that produce distinctive, though usually exceedingly small, physical effects. Quantum vacuum noise is familiar in optical and electronic devices, but in this paper I wish to consider extending the discussion to systems in which gravitation, or large accelerations, are impor...
متن کاملEffective scenario of loop quantum cosmology.
Semiclassical states in isotropic loop quantum cosmology are employed to show that the improved dynamics has the correct classical limit. The effective Hamiltonian for the quantum cosmological model with a massless scalar field is thus obtained, which incorporates also the next to leading order quantum corrections. The possibility that the higher order correction terms may lead to significant d...
متن کاملDynamical initial conditions in quantum cosmology.
Loop quantum cosmology is shown to provide both the dynamical law and initial conditions for the wave function of a universe by one discrete evolution equation. Accompanied by the condition that semiclassical behavior is obtained at large volume, a unique wave function is predicted.
