La transición del alumnado del instituto a la universidad es compleja y costosa. Durante las fases iniciales es donde se producen la mayor parte de los abandonos en las titulaciones de ingeniería. Los motivos son varios, pero los más destacados so

A Hamiltonian approach is introduced in order to address some severe problems associated with the physical description of the dynamical Casimir effect at all times. For simplicity, the case of a neutral scalar field in a one-dimensional cavity with p

We show the mathematical formulation of the process of pair production in electromagnetic fields for spinless particles. We compute the probability that ? pairs are created in the semiclassical approximation, and we prove that, in this approach, the

We will study the Klein-Gordon's field with an homogeneous external potential, which does not depend on ħ. We will construct the Fock's space corresponding to our problem and we will see that there are phenomena of creation and anihilation of pairs

In this paper we study the production of pairs in no-analytic potentials. It is a well-known fact that, when the potential is analytic the average number of produced pairs is exponentially small in ?. On the other hand, when the potential is no-analy

We will perform a detailed analysis of singularities in Einstein Cosmology and in LQC (Loop Quantum Cosmology). We will obtain explicit analytical expressions for the energy density and the Hubble constant for a given set of possible Equations of Sta

In this project we have performed an study of the singularities in Clasical Cosmology, considering a flat Friedmann-Lemaître-Robertson-Walker for a linear equation of state and for a non-linear one. We have computed analitically all the possible cas
