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…
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…
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…
