Complete entanglement detection using polynomial invariants
Thomas C. Fraser, Vjosa Blakaj, Roberto Rubboli +2
Existing methods for deciding whether a bipartite quantum state is separable or entangled typically fall into one of two categories: they are either complete but require access to…

Gibbs state postulate from dynamical stability -- Redundancy of the zeroth law
Vjosa Blakaj, Matthias C. Caro, Anouar Kouraich +2
Gibbs states play a central role in quantum statistical mechanics as the standard description of thermal equilibrium. Traditionally, their use is justified either by a heuristic, a…

On the set of reduced states of translation invariant, infinite quantum systems
Vjosa Blakaj, Michael M. Wolf
The set of two-body reduced states of translation invariant, infinite quantum spin chains can be approximated from inside and outside using matrix product states and marginals of f…
