Casimir effect in a quantum space-time
Rodolfo Gambini, Javier Olmedo, Jorge Pullin
We apply quantum field theory in quantum space-time techniques to study the Casimir effect for large spherical shells. As background we use the recently constructed exact quantum s…
Cosmological perturbations in Hybrid Loop Quantum Cosmology: Mukhanov-Sasaki variables
Laura Castelló Gomar, Mikel Fernández-Méndez, Guillermo A. Mena Marugán +1
We study cosmological perturbations in the framework of Loop Quantum Cosmology, using a hybrid quantization approach and Mukhanov-Sasaki variables. The formulation in terms of thes…
Effective dynamics of scalar perturbations in a flat Friedmann-Robertson-Walker spacetime in Loop Quantum Cosmology
Mikel Fernández-Méndez, Guillermo A. Mena Marugán, Javier Olmedo
We study the evolution of a homogeneous and isotropic spacetime whose spatial sections have three-torus topology, coupled to a massless scalar field with small scalar perturbations…
