Entanglement and permutational symmetry
Geza Toth, Otfried Gühne
We study the separability of permutationally symmetric quantum states. We show that for bipartite symmetric systems most of the relevant entanglement criteria coincide. However, we…
On superembedding approach to type IIB 7-branes
Igor A. Bandos
In search for a dynamical description of Q7-branes, which were known as solutions of supergravity equations and then conjectured to be dynamical objects of type IIB string theory,…
Entanglement detection
Otfried Gühne, Geza Toth
How can one prove that a given state is entangled? In this paper we review different methods that have been proposed for entanglement detection. We first explain the basic elements…
SDiff Gauge Theory and the M2 Condensate
Igor A. Bandos, Paul K. Townsend
We develop a general formalism for the construction, in -dimensional Minkowski space, of gauge theories for which the gauge group is the infinite-dimensional group SDiff of…
Spin squeezing and entanglement
Geza Toth, Christian Knapp, Otfried Gühne +1
What is the relation between spin squeezing and entanglement? To clarify this, we derive the full set of generalized spin squeezing inequalities for the detection of entanglement.…
