Shape coexistence in Sr isotopes
Esperanza Maya-Barbecho, José Enrique García-Ramos
Sr isotopes are located in the mass region , where a very quick onset of nuclear deformation exists, being other notable examples of this area Yb, Zr, and Nb nuclei.…
Evolution of octupole deformation and collectivity in neutron-rich lanthanides
K. Nomura, R. Rodríguez-Guzmán, L. M. Robledo +2
The onset of octupole deformation and its impact on related spectroscopic properties is studied in even-even neutron-rich lanthanide isotopes Xe, Ba, Ce, and Nd with neutron number…
Quadrupole-octupole coupling and the onset of octupole deformation in actinides
K. Nomura, R. Rodríguez-Guzmán, L. M. Robledo +1
The evolution of quadrupole and octupole collectivity and their coupling is investigated in a series of even-even isotopes of the actinide Ra, Th, U, Pu, Cm, and Cf with neutron nu…
The subtle connection between shape coexistence and quantum phase transition. The Zr case
J. E. García-Ramos, K. Heyde
Background: Zr region is characterized by very rapid changes in the ground state structure of the nuclei. In particular, the onset of deformation when passing from Zr to $^{…
Scaling Properties of the Lipkin Model at the Critical Point
J. M. Arias, J. E. García-Ramos
The influence of Franco Iachello in Physics during the last 50 years and, in particular, in the use of algebraic methods applied to very different physical problems has been broad,…
An extended Agassi model: algebraic structure, phase diagram, and large size limit
J. E. García-Ramos, J Dukelsky, P Pérez-Fernández +1
The Agassi model is a schematic two-level model that involves pairing and monopole-monopole interactions. It is, therefore, an extension of the well known Lipkin-Meshkov-Glick (LMG…
