Introduction to Quantum Entanglement
... Consider completely positive map Λ and state ρA ⊗ρB . The state ρA ⊗ρB is positive thus (1l⊗Λ)(ρA ⊗ρB ) = ρA ⊗Λ(ρB ) is positive. Map Λ is positive for all states also for entangled ones, hence Λ cannot be used for the detection of entanglement. The above property is important for the recognizing en ...

Symmetry breaking - Corso di Fisica Nucleare
... Here we collect two definitions of Spontaneous Symmetry Breaking (SSB)2 : 1. Generally, the breaking of a certain symmetry does not imply that no symmetry is present, but rather that the situation where this symmetry is broken is characterized by a lower symmetry. In group theoretic terms, this mean ...
