No-go theorems for pointwise-defined spinorial quantum fields
Samuel Fedida
We extend and strengthen no-go results on pointwise-defined quantum fields to cover general spinors. We show that the weak continuity of quantum fields rules out equal-time canonic…
The thermodynamics of readout devices and semiclassical gravity
Samuel Fedida, Adrian Kent
We analyse the common claim that nonlinear modifications of quantum theory necessarily violate the second law of thermodynamics. We focus on hypothetical extensions of quantum theo…
Foundations of Relational Quantum Field Theory I: Scalars
Samuel Fedida, Jan Głowacki
We develop foundations for a relational approach to quantum field theory (RQFT) based on the operational quantum reference frames (QRFs) framework considered in a relativistic sett…
Einstein causality of quantum measurements in the Tomonaga-Schwinger picture
Samuel Fedida
We investigate a generalisation to Lüders' rule à la Aharonov-Albert in those globally hyperbolic spacetimes which allow unitarily equivalent Hilbert spaces to be defined along Cau…
