Decomposition of symmetric separable states and ground state energy of bosonic systems
Stephan Weis
We prove that every symmetric separable state admits a convex decomposition into symmetric pure product states. While the result is not new in itself, here we focus on convex geome…

Extreme points of the set of quantum states with bounded energy
Stephan Weis, Maksim Shirokov
We show that for any energy observable every extreme point of the set of quantum states with bounded energy is a pure state. This allows us to write every state with bounded energy…
