Nonlocality, Integrability and Quantum Chaos in the Spectrum of Bell Operators
Albert Aloy, Guillem Müller-Rigat, Maciej Lewenstein +2
We introduce a permutationally invariant multipartite Bell inequality for many-body three-level systems and use it to investigate a connection between Bell nonlocality and (lack of…

Sufficient criteria for absolute separability in arbitrary dimensions via linear map inverses
Jofre Abellanet-Vidal, Guillem Müller-Rigat, Grzegorz Rajchel-MieldzioÄ +1
Quantum states that remain separable (i.e., not entangled) under any global unitary transformation are known as absolutely separable and form a convex set. Despite extensive effort…

Symmetric quantum states: a review of recent progress
Carlo Marconi, Guillem Müller-Rigat, Jordi Romero-Pallejà +2
Symmetric quantum states are fascinating objects. They correspond to multipartite systems that remain invariant under particle permutations. This symmetry is reflected in their com…
