dc.description.abstract | The quantum phase transition studies we have done during the last few years for odd-even
systems are reviewed. The focus is on the quantum shape phase transition in Bose-Fermi systems.
They are studied within the Interacting Boson-Fermion Model (IBFM). The geometry is included in
this model by using the intrinsic frame formalism based on the concept of coherent states. First, the
critical point symmetries E(5/4) and E(5/12) are summarized. E(5/4) describes the case of a single
j = 3/2 particle coupled to a bosonic core that undergoes a transition from spherical to γ-unstable.
E(5/12) is an extension of E(5/4) that describes the multi-j case (j = 1/2, 3/2, 5/2) along the same
transitional path. Both, E(5/4) and E(5/12), are formulated in a geometrical context using the Bohr
Hamiltonian. Similar situations can be studied within the IBFM considering the transitional path
from UBF(5) to OBF(6). Such studies are also presented. No critical points have been proposed for
other paths in odd-even systems as, for instance, the transition from spherical to axially deformed
shapes. However, the study of such shape phase transition can be done easily within the IBFM
considering the path from UBF(5) (spherical) to SUBF(3) (axial deformed). Thus, in a second part,
this study is presented for the multi-j case. Energy levels and potential energy surfaces obtained
within the intrinsic frame formalism of the IBFM Hamiltonian are discussed. Finally, our recent
works within the IBFM for a single-j fermion coupled to a bosonic core that performs different shape
phase transitional paths are reviewed. All significant paths in the model space are studied: from
spherical to γ-unstable shape, from spherical to axially deformed (prolate and oblate) shapes, and
from prolate to oblate shape passing through the γ-unstable shape. The aim of these applications is
to understand the effect of the coupled fermion on the core when moving along a given transitional
path and how the coupled fermion modifies the bosonic core around the critical points. | es |
