A new entanglement measure induced by the Hilbert-Schmidt norm
C. Witte, M. Trucks
In this letter we discuss a new entanglement measure. It is based on the Hilbert-Schmidt norm of operators. We give an explicit formula for calculating the entanglement of a large…
On Bose-Einstein condensation on closed Robertson-Walker spacetimes
M. Trucks
In this letter we summarize our analysis of Bose-Einstein condensation on closed Robertson-Walker spacetimes. In a previous work we defined an adiabatic KMS state on the Weyl-algeb…
A KMS-like state of Hadamard type on Robertson-Walker spacetimes and its time evolution
Mathias Trucks
In this work we define a new state on the Weyl algebra of the free massive scalar Klein-Gordon field on a Robertson-Walker spacetime and prove that it is a Hadamard state. The stat…
Correlations of Quantum Fields on Robertson-Walker Spacetimes
Mathias Trucks
It is a well known fact that quantum fields on Minkowski spacetime are correlated for each pair of spacetime regions. In Robertson-Walker spacetimes there are spacelike separated r…
