N-tangle, Entangled Orthonormal Basis, and a Hierarchy of Spin Hamilton Operators
نویسندگان
چکیده
An N-tangle can be defined for the finite dimensional Hilbert space H = C2N , with N = 3 or N even. We give an orthonormal basis which is fully entangled with respect to this measure. We provide a spin Hamilton operator which has this entangled basis as normalized eigenvectors if N is even. From these normalized entangled states a Bell matrix is constructed and the cosine–sine decomposition is calculated. If N is odd the normalized eigenvectors can be entangled or unentangled depending on the parameters.

Spin Networks and Recoupling in Loop Quantum Gravity 1;2
I discuss the role played by the spin-network basis and recoupling theory (in its graphical tangle-theoretic formulation) and their use for performing explicit calculations in loop quantum gravity. In particular, I show that recoupling theory allows the derivation of explicit expressions for the eingenvalues of the quantum volume operator. An important side result of these computations is the d...

متن کاملF eb 2 01 3 Exceptional Points , Nonnormal Matrices , Hierarchy of Spin Matrices and an Eigenvalue Problem
Kato [1] (see also Rellich [2]) introduced exceptional points for singularities appearing in the perturbation theory of linear operators. Afterwards exceptional points and energy level crossing have been studied for hermitian Hamilton operators [3, 4, 5, 6, 7, 8, 9, 10] and non-hermitian Hamilton operators [11, 12, 13, 14, 15, 16] by many authors. Here we consider the finite dimensional Hilbert...
متن کاملNew characterizations of fusion bases and Riesz fusion bases in Hilbert spaces
In this paper we investigate a new notion of bases in Hilbert spaces and similar to fusion frame theory we introduce fusion bases theory in Hilbert spaces. We also introduce a new denition of fusion dual sequence associated with a fusion basis and show that the operators of a fusion dual sequence are continuous projections. Next we dene the fusion biorthogonal sequence, Bessel fusion basis, Hil...
متن کاملG-Frames, g-orthonormal bases and g-Riesz bases
G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.
