Notes on dark energy interacting with dark matter and unparticle in loop quantum cosmology
Notes dark energy dark matter unparticle loop quantum cosmology
2011/8/3
Abstract: We investigate the behavior of dark energy interacting with dark matter and unparticle in the framework of loop quantum cosmology. In four toy models, we study the interaction between the co...
On the measure problem in slow roll inflation and loop quantum cosmology
measure problem slow roll inflation loop quantum cosmology
2010/12/20
We consider the measure problem in standard slow-roll in ationary models from the perspective
of loop quantum cosmology (LQC).
Inflationary observables in loop quantum cosmology
Inflationary observables loop quantum cosmology
2010/12/20
The full set of cosmological observables coming from linear scalar and tensor perturbations of loop quantum cosmology is computed in the presence of inverse-volume corrections.
Path Integrals and the WKB approximation in Loop Quantum Cosmology
Path Integrals WKB approximation Loop Quantum Cosmology
2010/12/20
We follow the Feynman procedure to obtain a path integral formulation of loop quantum cosmology starting from the Hilbert space framework. Quantum geometry effects modify the weight associated with ea...
Bianchi I model in terms of nonstandard loop quantum cosmology: Quantum dynamics
Bianchi I model terms nonstandard loop quantum cosmology Quantum dynamics
2010/11/9
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 the volume operator i...
On the one hand, inflation is an extremely convincing scenario: it solves most cosmological paradoxes and generates fluctuations that became the seeds for the growth of structures. It, however,suffers...

Loop cosmology big bounce spectra of physical observables free parameter
2010/3/18
We present results concerning the nature of the cosmological big bounce(BB) transition within the loop geometry underlying loop quantum cosmology (LQC). Our canonical quantization method is an alterna...
Cosmic recall and the scattering picture of Loop Quantum Cosmology
Cosmic recall scattering picture Loop Quantum Cosmology
2010/3/17
The global dynamics of a homogeneous universe in Loop Quantum Cosmology is viewed as a scattering process of its geometrodynamical equivalent. This picture is applied to build a flexible (easy to gene...
After introducing the basic ingredients of Loop Quantum Cosmology, I will briefly discuss some of its phenomenological aspects. Those can give some useful insight about the full Loop Quantum Gravity t...
