Intrinsic Heisenberg-type lower bounds on spacelike hypersurfaces in general relativity
Thomas Schürmann
In quantum theory on curved backgrounds, Heisenberg's uncertainty principle is usually discussed in terms of ensemble variances and flat-space commutators. Here we take a different…

The Extended Uncertainty Principle from a Projector-Valued Measurement Perspective
Thomas Schürmann
We revisit the Extended Uncertainty Principle (EUP) from an operational viewpoint, replacing wavefunction-based widths with apparatus-defined position constraints such as a finite…
