Let N(Z) denote the number of electrons which a nucleus of charge Z can bind in non-relativistic quantum mechanics (assuming that electrons are fermions). We prove that JV(Z)/Z-> 1 as Z-> oo.

The anyon fields have trivial Î±-commutator for Î± not integer. For integer Î± the commutators become temperature-dependent operator valued distributions. The n-point functions do not factorize as forâ€¦ (More)

We work in the real Hilbert space Hs of hermitian Hilbert-Schmid operators and show that the entanglement witness which shows the maximal violation of a generalized Bell inequality (GBI) is a tangentâ€¦ (More)

We construct an axiomatic framework for a quantum mechanical extension to the theory of Anosov systems, and show that this retains some of the characteristic features of its classical counterpart,â€¦ (More)

Quantum entanglement has become a resource for the fascinating developments in quantum information and quantum communication during the last decades. It quantifies a certain nonclassical correlationâ€¦ (More)

Semigroups describing the time evolution of open quantum systems in finite dimensional spaces have generators of a special form, known as Lindblad generators. The simple generators, characterized byâ€¦ (More)

We prove that for a von Neumann algebra that is an algebraic K system with respect to some automorphism, the invariant state is K{clustering and r{clustering. Further we study in examples how far theâ€¦ (More)

We consider a BCS-type model in the spin formalism and argue that the structure of the interaction provides a mechanism for control over directions of the spin âˆ’ â†’ S other than Sz, which is beingâ€¦ (More)
