Spin Hamiltonian with large fourth order terms: Triple well potentials and Bloch sphere visualization
D. S. Lohr Robles, M. Grether, E. Lopez Moreno +1
We present a study of a general spin Hamiltonian with terms up to fourth order. With the coherent states the semiclassical potential is obtained and with catastrophe theory its par…
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…
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…
Quantum Phase Transitions within a nuclear cluster model and an effective model of QCD
David S. Lohr-Robles, Enrique Lopez-Moreno, Peter O. Hess
The catastrophe theory is applied to a nuclear cluster model and an effective model for QCD at low energy. The study of quantum phase transitions in the cluster model was considere…
Axial and polar modes for the ring down of a Schwarzschild black hole with an r dependent mass-function
Peter Otto Hess, Enrique Lopez-Moreno
The axial and polar modes for the ring down of a Schwarzschild black hole are calculated, by first deriving the Regge-Wheeler and Zerilli equations, respectively, and finally apply…
Coherent State Description of the Ground State in the Tavis-Cummings Model and its Quantum Phase Transitions
Octavio Castanos, Ramon Lopez-Pena, Eduardo Nahmad-Achar +3
Quantum phase transitions and observables of interest of the ground state in the Tavis-Cummings model are analyzed, for any number of atoms, by using a tensorial product of coheren…
