A local diagnostic program for unitary evolution in general space-times
Ka Hei Choi, Stefan Hofmann, Marc Schneider
We present a local framework for investigating non-unitary evolution groups pertinent to effective field theories in general semi-classical spacetimes. Our approach is based on a r…

Emerging entanglement on network histories
Cecilia Giavoni, Stefan Hofmann, Maximilian Koegler
We show that quantum fields confined to Lorentzian histories of freely falling networks in Minkowski spacetime probe entanglement properties of vacuum fluctuations that extend unre…
