An order $2 m $ complex tensor $\cH $ is said to be Hermitian if\[\mathcal {H} _\ijm=\mathcal {H} _\jim^*\mathrm {\for\all\}\ijm.\] It can be regarded as an extension of Hermitian matrix to …
Hermitian tensors are natural generalizations of Hermitian matrices, while possessing rather different properties. A Hermitian tensor is separable if it has a Hermitian decomposition with …

In our paper, we concentrate on the Z-eigenvalue inclusion theorem and its application in the geometric measure of entanglement of multipartite pure states. We present a new Z …
The geometric measure of entanglement of a multipartite pure state is defined it terms of its geometric distance from the set of separable pure states. The quantum eigenvalue problem …
