Global geometric difference between separable and Positive partial transpose states
Kil-Chan Ha, Seung-Hyeok Kye
In the convex set of all $3\ot 3$ states with positive partial transposes, we show that one can take two extreme points whose convex combinations belong to the interior of the conv…

Geometry for separable states and construction of entangled states with positive partial transposes
Kil-Chan Ha, Seung-Hyeok Kye
We construct faces of the convex set of all bipartite separable states, which are affinely isomorphic to the simplex with ten extreme points. Every interior po…

Faces for two qubit separable states and the convex hulls of trigonometric moment curves
Seung-Hyeok Kye
We analyze the facial structures of the convex set consisting of all two qubit separable states. One of faces is a four dimensional convex body generated by the trigonometric momen…
