Query: Two-neutron transfer reactions and shape phase transitions in the
  microscopically-formulated interacting boson model   Two-neutron transfer reactions are studied within the interacting boson model
based on the nuclear energy density functional theory. Constrained
self-consistent mean-field calculations with the Skyrme energy density
functional are performed to provide microscopic input to completely determine
the Hamiltonian of the IBM. Spectroscopic properties are calculated only from
the nucleonic degrees of freedom. This method is applied to study the $(t,p)$
and $(p,t)$ transfer reactions in the assorted set of rare-earth nuclei
$^{146-158}$Sm, $^{148-160}$Gd, and $^{150-162}$Dy, where
spherical-to-axially-deformed shape phase transition is suggested to occur at
the neutron number $N\approx 90$. The results are compared with those from the
purely phenomenological IBM calculations, as well as with the available
experimental data. The calculated $(t,p)$ and $(p,t)$ transfer reaction
intensities, from both the microscopic and phenomenological IBM frameworks,
signal the rapid nuclear structural change at particular nucleon numbers.
