Examination of the nature of the Bianchi type cosmological singularities

Piotr Dzierzak

We present quantum (and classical) Bianchi I model, with free massless scalar field, of the Universe. Our model may be treated as the simplest prototype of the quantum BKL (Belinsk…

Bianchi I model in terms of nonstandard loop quantum cosmology: Quantum dynamics

Przemyslaw Malkiewicz, Wlodzimierz Piechocki, Piotr Dzierzak

We analyze the quantum Bianchi I model in the setting of the nonstandard loop quantum cosmology. Elementary observables are used to quantize the volume operator. The spectrum of th…

Bianchi I model in terms of nonstandard loop quantum cosmology: Classical dynamics

Piotr Dzierzak, Wlodzimierz Piechocki

The cosmological singularities of the Bianchi I universe are analyzed in the setting of loop geometry underlying the loop quantum cosmology. We solve the Hamiltonian constraint of…

Turning Big Bang into Big Bounce: I. Classical Dynamics

Piotr Dzierzak, Przemyslaw Malkiewicz, Wlodzimierz Piechocki

The big bounce (BB) transition within a flat Friedmann-Robertson-Walker model is analyzed in the setting of loop geometry underlying the loop cosmology. We solve the constraint of…

The minimum length problem of loop quantum cosmology

Piotr Dzierzak, Jacek Jezierski, Przemyslaw Malkiewicz +1

The appearance of the big bounce (BB) in the evolution of the universe is analyzed in the setting of loop quantum cosmology (LQC). Making use of an idea of a minimum length turns c…
