Competing topological orders in three dimensions: X-cube versus toric code
M. Mühlhauser, K. P. Schmidt, J. Vidal +1
We study the competition between two different topological orders in three dimensions by considering the X-cube model and the three-dimensional toric code. The corresponding Hamilt…
Ising versus string-net ladder
J. Vidal
We consider the string-net model obtained from fusion rules. These fusion rules are shared by two different sets of anyon theories. In this work, we study the competition…
Two-level interacting boson models beyond the mean field
J. M. Arias, J. Dukelsky, J. E. Garcia-Ramos +1
The phase diagram of two-level boson Hamiltonians, including the Interacting Boson Model (IBM), is studied beyond the standard mean field approximation using the Holstein-Primakoff…
Entanglement dynamics in the Lipkin-Meshkov-Glick model
J. Vidal, G. Palacios, Cl. Aslangul
The dynamics of the one-tangle and the concurrence is analyzed in the Lipkin-Meshkov-Glick model which describes many physical systems such as the two-mode Bose-Einstein condensate…
Entanglement in a first order quantum phase transition
J. Vidal, R. Mosseri, J. Dukelsky
The phase diagram of spins 1/2 embedded in a magnetic field mutually interacting antiferromagnetically is determined. Contrary to the ferromagnetic case where a second order quantu…
Randomly dilute Ising model: A nonperturbative approach
M. Tissier, D. Mouhanna, J. Vidal +1
The N-vector cubic model relevant, among others, to the physics of the randomly dilute Ising model is analyzed in arbitrary dimension by means of an exact renormalization-group equ…
