Inflationary scenarios in Starobinsky model with higher order corrections
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We consider the Starobinsky inflation with a set of higher order corrections parametrised by two real coefficients . In the Einstein frame we have found a potential with…
Strongly Coupled Perturbations in Two-Field Inflationary Models
Sera Cremonini, Zygmunt Lalak, Krzysztof Turzynski
We study models of inflation with two scalar fields and non-canonical kinetic terms, focusing on the case in which the curvature and isocurvature perturbations are strongly coupled…
Non-minimal Gauge Mediation and Moduli Stabilization
T. Jelinski, Z. Lalak, J. Pawelczyk
In this paper we consider U(1)-gauged Polony'i model with two spurions coupled to a twisted closed string modulus. This offers a consistent setup for metastable SUSY breakdown whic…
Loop Quantum Cosmology corrections to inflationary models
Michal Artymowski, Zygmunt Lalak, Lukasz Szulc
In the recent years the quantization methods of Loop Quantum Gravity have been successfully applied to the homogeneous and isotropic Friedmann-Robertson-Walker space-times. The res…
Scalar field fluctuations in Pre-Big-Bang Cosmologies
Z. Lalak, R. Poppe
Jordan-Brans-Dicke theories with a linearized potential for the scalar field are investigated in the framework of the stochastic approach. The fluctuations of this field are examin…
