Continuous unitary transformations in two-level boson systems

Dusuel, Sébastien; Vidal, Julien; Arias Carrasco, José Miguel; Dukelsky, J.; García Ramos, José Enrique (American Physical Society, 2005-12-30)

Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with O(2L + 1) symmetry for large number of ...
Finite-size scaling exponents in the interacting boson model

Dusuel, Sébastien; Vidal, Julien; Arias Carrasco, José Miguel (American Physical Society, 2005-07-14)

We investigate the finite-size scaling exponents for the critical point at the shape phase transition from U(5) (spherical) to O(6) (deformed -unstable) dynamical symmetries of the Interacting Boson Model, making use ...
