Monte Carlo quantum cosmology with a modified Euclidean action
Malaik Kabir, Syed Moeez Hassan
We numerically study the Euclidean quantum cosmology of a closed, homogeneous and isotropic universe with a cosmological constant. A dust field acts as a clock, and we compute the…

Semiclassical polymer field with a cubic potential in cosmology
Ahsan Mujtaba, Syed Moeez Hassan
We study the semiclassical dynamics of a polymer quantized scalar field with a cubic potential in cosmology. The cosmological spacetime is chosen to be homogeneous and isotropic, a…

Polymer cosmology with polymer matter: Effective dynamics
Aleena Zulfiqar, Syed Moeez Hassan
We study the effective dynamics of a polymer quantized scalar field living on an effective polymer quantized homogeneous and isotropic background. We use a presureless dust field a…
