Stable quantum systems in anti-de Sitter space: Causality, independence and spectral properties
Detlev Buchholz, Stephen J. Summers
If a state is passive for uniformly accelerated observers in n-dimensional anti-de Sitter space-time (i.e. cannot be used by them to operate a perpetuum mobile), they will (a) regi…

Geometric modular action and spontaneous symmetry breaking
Detlev Buchholz, Stephen J. Summers
We study spontaneous symmetry breaking for field algebras on Minkowski space in the presence of a condition of geometric modular action (CGMA) proposed earlier as a selection crite…

Quantum statistics and locality
Detlev Buchholz, Stephen J. Summers
It is shown that two observers have mutually commuting observables if they are able to prepare in each subsector of their common state space some state exhibiting no mutual correla…
