First order phase transition in the anisotropic quantum orbital compass model
Roman Orus, Andrew C. Doherty, Guifre Vidal
We investigate the anisotropic quantum orbital compass model on an infinite square lattice by means of the infinite projected entangled-pair state algorithm. For varying values of…

Geometric Entanglement in a One-Dimensional Valence Bond Solid State
Roman Orus
In this paper we provide the analytical derivation of the global geometric entanglement per block for the valence bond solid ground state of the spin-1 AKLT chain. In particular, w…

Equivalence of critical scaling laws for many-body entanglement in the Lipkin-Meshkov-Glick model
R. Orus, S. Dusuel, J. Vidal
We establish a relation between several entanglement properties in the Lipkin-Meshkov-Glick model, which is a system of mutually interacting spins embedded in a magnetic field. We…
