Classical Bianchi type I cosmology in K-essence theory
J. Socorro, Luis O. Pimentel, Abraham Espinoza-García
We use one of the simplest forms of the K-essence theory and we apply it to the classical anisotropic Bianchi type I cosmological model, with a barotropic perfect fluid modeling th…
Cosmological Bianchi Class A models in Sáez-Ballester theory
J. Socorro, Paulo A. Rodríguez, Abraham Espinoza-García +2
We use the Sáez-Ballester (SB) theory on anisotropic Bianchi Class A cosmological model, with barotropic fluid and cosmological constant, using the Hamilton or Hamilton-Jacobi appr…
Dual symmetry and the vacuum energy
V. I. Tkach, J. Socorro, J. J. Rosales +1
In this work we present a new hidden symmetry in gravity for the scale factor in the FRW model, for . This exact symmetry vanishes the cosmological constant. We interpret this…
Supersymmetric one-parameter strict isospectrality for the attractive delta potentials
L. J. Boya, H. C. Rosu, A. J. Segui-Santonja +2
The Schrödinger equation with attractive delta potential has been previously studied in the supersymmetric quantum mechanical approach by a number of authors, but they all used onl…
Supersymmetric double Darboux method in quantum cosmology
J. Socorro, H. C. Rosu
We briefly present the supersymmetric double Darboux method and next apply it to the continuum of the quantum Taub cosmological model as a toy model in order to generate a one-para…
One-parameter family of closed, radiation-filled Friedmann-Robertson-Walker ``quantum'' universes
H. C. Rosu, J. Socorro
Using as an illustrative example the p=1 operator-ordered Wheeler-DeWitt equation for a closed, radiation-filled Friedmann-Robertson-Walker universe, we introduce and discuss the s…
