Physical Review Letters. Vol. 93, n. 21 (2004). ISSN 0031-90070031-9007http://hdl.handle.net/10272/5462We 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.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/BosonesBoson modelQuantum phase transitionsproton–neutronjournal articleopen access
