Entanglement and factorized ground states in two-dimensional quantum antiferromagnets
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
Making use of exact results and quantum Monte Carlo data for the entanglement of formation, we show that the ground state of anisotropic two-dimensional S=1/2 antiferromagnets in a…
Entanglement in quantum critical spin systems
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
We study the field dependence of the entanglement of formation in anisotropic S=1/2 antiferromagnetic chains and two-leg ladders displaying a T=0 field-driven quantum phase transit…
Quantum percolation in two-dimensional antiferromagnets
Rong Yu, Tommaso Roscilde, Stephan Haas
The interplay of geometric randomness and strong quantum fluctuations is an exciting topic in quantum many-body physics, leading to the emergence of novel quantum phases in strongl…
Studying quantum spin systems through entanglement estimators
Tommaso Roscilde, Paola Verrucchi, Andrea Fubini +2
We study the field dependence of the entanglement of formation in anisotropic S=1/2 antiferromagnetic chains displaying a T=0 field-driven quantum phase transition. The analysis is…
Anisotropy-induced ordering in the quantum J1-J2 antiferromagnet
Tommaso Roscilde, Adrian Feiguin, Alexander L. Chernyshev +2
We study the effect of spin anisotropies on a frustrated quantum antiferromagnet using the J_1-J_2^{XXZ} model on the square lattice. The T=0 and finite-T phase diagrams of this mo…
