FRW cosmological model inside an isolated Schwarzschild black hole
C. Ortiz, J. J. Rosales, J. Socorro +1
Using the canonical quantum theory of spherically symmetric pure gravitational systems, we present a direct correspondence between the Friedmann-Robertson-Walker (FRW) cosmological…
Classical solutions from quantum regime for barotropic FRW model
J. Socorro
The quantization of gravity coupled to barotropic perfect fluid as matter field and cosmological constant is made and the wave function can be determined for any in the FRW min…
Supersymmetric quantum solution for FRW cosmological model with matter
J. Socorro
Using technique of supersymmetric quantum mechanics we present new cosmological quantum solution, in the regime for FRW cosmological model using a barotropic perfect fluid as matte…
Family of solutions for axisymmetric electrovacuum Einstein-Maxwell field equations
J. Socorro, Octavio Cornejo Perez
We present a family of solutions for the axisymmetric Plebanski-Demianski metric and other corresponding reduced metrics. We also present the black hole characteristics using a new…
Ermakov approach for minisuperspace oscillators
H. C. Rosu, J. Socorro
The WDW equation of arbitrary Hartle-Hawking factor ordering for several minisuperspace universe models, such as the pure gravity FRW and Taub ones, is mapped onto the dynamics of…
The wave function of the universe and spontaneaus breaking of supersymmetry
O. Obregón, J. J. Rosales, J. Socorro +1
In this work we define a scalar product ``weighted'' with the scalar factor and show how to find a normalized wave function for the supersymmetric quantum FRW cosmological mode…
