Weakly-entangled states are dense and robust
Roman Orus, Rolf Tarrach
Motivated by the mathematical definition of entanglement we undertake a rigorous analysis of the separability and non-distillability properties in the neighborhood of those three-q…

Quantum Phase Transitions in Anti-ferromagnetic Planar Cubic Lattices
Cameron Wellard, Roman Orus
Motivated by its relation to an -hard problem, we analyze the ground state properties of anti-ferromagnetic Ising-spin networks embedded on planar cubic lattices, under t…
