Information-theoretic aspects of quantum inseparability of mixed states [PDF]

, 1996
Information-theoretic aspects of quantum inseparability of mixed states are investigated in terms of the $\alpha$-entropy inequalities and teleportation fidelity.

K2[FeII3(P2O7)2(H2O)2]

Acta Crystallographica Section E, 2012
The title compound, dipotassium diaquabis(diphosphato)triferrate(II), K2[FeII3(P2O7)2(H2O)2], was synthesized under solvothermal conditions. The crystal structure is isotypic with its Co analogue.

Aluminium cyclohexaphosphate

Acta Crystallographica Section E, 2010
Single crystals of the title compound, Al2P6O18, were obtained by solid-state reaction. The monoclinic structure is isotypic with its CrIII, GaIII and RuIII analogues and is built up of six-membered phosphate ring anions, P6O186−, isolated from

Defect of an octahedron in a rational lattice [PDF]

Discrete Applied Mathematics, 2019
Consider an arbitrary $n$-dimensional lattice $ $ such that $\mathbb{Z}^n \subset \subset \mathbb{Q}^n$. Such lattices are called {\it rational} and can always be obtained by adding $m \le n$ rational vectors to $\mathbb{Z}^n$. {\it Defect } $d({\cal E}, )$ of the standard basis $ {\cal E}$ of ${\mathbb Z}^n$ ($n$ unit vectors going in the ...

On the classification of discrete Hirota-type equations in 3D [PDF]

, 2013
In the series of recent publications we have proposed a novel approach to the classification of integrable differential/difference equations in 3D based on the requirement that hydrodynamic reductions of the corresponding dispersionless limits are ...

Inscribing a regular octahedron into polytopes

Discrete Mathematics, 2013
We prove that any simple polytope (and some non-simple polytopes) in $\mathbb R^3$ admits an inscribed regular octahedron.

Comparative Study of Prism Octahedron Network via Eccentric Invariants

Journal of Chemistry, 2023
Topological indices are empirical features of graphs that characterize the topology of the graph and, for the most part, are graph independent. An important branch of graph theory is chemical graph theory.
