Phase diagram of the proton-neutron interacting boson model
Arias Carrasco, José Miguel; García Ramos, José Enrique; Dukelsky, Jorge (American Physical Society, 2004-11-19)We study the phase diagram of the proton-neutron interacting boson model with special emphasis on the phase transitions leading to triaxial phases. The existence of a new critical point between spherical and triaxial shapes is reported.

Quantum phase transitions in the interacting boson model: Integrability, level repulsion, and level crossing
Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique (American Physical Review, 2003-10-17)We study the quantum phase transition mechanisms that arise in the interacting boson model. We show that the second-order ...

Quantum phase transitions of atom-molecule Bose mixtures in a double-well potential
Arias Carrasco, José Miguel; Relaño, Armando; Dukelsky, Jorge; Pérez Fernández, Pedro (2014)The ground state and spectral properties of Bose gases in double-well potentials are studied in two different scenarios: ...

Quantum quench influenced by an excited-state phase transition
Pérez Fernández, Pedro; Cejnar, P.; Arias Carrasco, José Miguel; Dukelsky, Jorge; García Ramos, José Enrique; Relaño, Armando (American Physical Society, 2011)We analyze excited-state quantum phase transitions (ESQPTs) in three schematic (integrable and nonintegrable) models ...

Scalar two-level boson model to study the interacting boson model phase diagram in the Casten triangle
Arias Carrasco, José Miguel; García Ramos, José Enrique; Vidal, Julien; Dukelsky, Jorge (American Physical Society, 2006)We introduce a simple two-level boson model with the same energy surface as the Q-consistent interacting boson model ...

U(5)-O(6) transition in the interacting boson model and the E(5) critical point symmetry
Arias Carrasco, José Miguel; Alonso Alonso, Clara Eugenia; Vitturi, Andrea; García Ramos, José Enrique; Dukelsky, Jorge; Frank, A. (American Physical Society, 2003-10-01)The relation of the recently proposed E(5) critical point symmetry with the interacting boson model is ...

β4 potential at the U(5)–O(6) critical point of the interacting boson model
García Ramos, José Enrique; Dukelsky, Jorge; Arias Carrasco, José Miguel (American Physical Society, 2005)Exact numerical results of the interacting boson model Hamiltonian along the integrable line from U(5) to O(6) are obtained ...
