Continuous unitary transformations in two-level boson systems
S. Dusuel, J. Vidal, J. M. Arias +2
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…

Finite-size scaling exponents in the interacting boson model
S. Dusuel, J. Vidal, J. M. Arias +2
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…

Finite-Size Scaling Exponents of the Lipkin-Meshkov-Glick Model
S. Dusuel, J. Vidal
We study the ground state properties of the critical Lipkin-Meshkov-Glick model. Using the Holstein-Primakoff boson representation, and the continuous unitary transformation techni…
