Shape evolution and the role of intruder configurations in Hg isotopes within the interacting boson model based on a Gogny energy density functional
K. Nomura, R. Rodriguez-Guzman, L. M. Robledo
The interacting boson model with configuration mixing, with parameters derived from the self-consistent mean-field calculation employing the microscopic Gogny energy density functi…
Microscopic description of quadrupole-octupole coupling in Sm and Gd isotopes with the Gogny Energy Density Functional
R. Rodriguez-Guzman, L. M. Robledo, P. Sarriguren
The interplay between the collective dynamics of the quadrupole and octupole deformation degree of freedom is discussed in a series of Sm and Gd isotopes both at the mean field lev…
Shape coexistence in Lead isotopes in the interacting boson model with Gogny energy density functional
K. Nomura, R. Rodriguez-Guzman, L. M. Robledo +1
We investigate the emergence and evolution of shape coexistence in the neutron-deficient Lead isotopes within the interacting boson model (IBM) plus configuration mixing with micro…
N-electron Slater determinants from non-unitary canonical transformations of fermion operators
Carlos A. Jimenez-Hoyos, R. Rodriguez-Guzman, Gustavo E. Scuseria
Mean-field methods such as Hartree-Fock (HF) or Hartree-Fock-Bogoliubov (HFB) constitute the building blocks upon which more elaborate many-body theories are based on. The HF and H…
Symmetry-projected variational approach for ground and excited states of the two-dimensional Hubbard model
R. Rodríguez-Guzmán, K. W. Schmid, Carlos A. Jiménez-Hoyos +1
We present a symmetry-projected configuration mixing scheme to describe ground and excited states, with well defined quantum numbers, of the two-dimensional Hubbard model with near…
