Semiclassical study of single-molecule magnets and their quantum phase transitions
David Stefan, Lohr-Robles, Enrique +2
We present a study of systems of single-molecule magnets using a semiclassical analysis and catastrophe theory. Separatrices in parameter space are constructed which are useful to…
The Branch-cut Cosmology: A topological canonical quantum approach
Peter O. Hess, César A. Zen Vasconcellos, José de Freitas Pacheco +2
In this contribution we sketch a branch-cut quantum formulation of the Wheeler-DeWitt equation analytically continued to the complex plane. As a starting point, we base our approac…
The Branch-Cut Cosmology: evidences and open questions
César A. Zen Vasconcellos, Peter O. Hess, José de Freitas Pacheco +2
In this work we present a brief summary of the branch-cut cosmology as well as we approach topics not yet explored. Starting with an already explored topic, the theme of primordial…
Causality and the Arrow of Time in the Branch-Cut Cosmology
Benno Bodmann, César A. Zen Vasconcellos, José de Freitas Pacheco +2
We basis our initial analysis of the arrow of time on a relationship between the time evolution operator of quantum system and the time-independent density operator which describes…
Branch-Cut Cosmology and the Bekenstein Criterion
José A. de Freitas Pacheco, César A. Zen Vasconcellos, Peter O. Hess +2
In this contribution we address the implications of the Bekenstein Criterion in the branch-cut cosmology. The impossibility of packaging energy and entropy according to the Bekenst…
Application of the cranking method to the semimicroscopic algebraic cluster model and nuclear molecules
David Stefan Lohr-Robles, Giovani Erick Morales-Hernández, Enrique Lopez-Moreno +1
A particular quantum phase transition (QPT) is studied at excited energies of light nuclei within the Semimicroscopic Algebraic Cluster Model (SACM), using a combination of catastr…
