Quantum Ontology in the Light of Gauge Theories [PDF]
, 2011 We propose the conjecture according to which the fact that quantum mechanics does not admit sharp value attributions to both members of a complementary pair of observables can be understood in the light of the symplectic reduction of phase space in ...

Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies
European Physical Journal C: Particles and FieldsIn bouncing cosmological models – whether classical or quantum – the big bang singularity is replaced by a regular bounce. A well-known challenge is controlling the growth of shear during the contracting phase, as the shear scales as $$a^{-6}$$ a - 6 ...

Loop Quantum Cosmology and Boundary Proposals
For many years, the most active area of quantum cosmology has been the issue of choosing boundary conditions for the wave function of a universe. Recently, loop quantum cosmology, which is obtained from loop quantum gravity, has shed new light on this ...

Onset of inflation in loop quantum cosmology
, 2007 Using a Liouville measure, similar to the one proposed recently by Gibbons and Turok, we investigate the probability that single-field inflation with a polynomial potential can last long enough to solve the shortcomings of the standard hot big bang model,
