How to measure quantum fields? Implementing a causal measurement scheme

Jan Mandrysch (Wien)

While measurement processes in standard quantum mechanics are well understood, the extension of these ideas to quantum field theory (QFT) remains a key challenge. In particular, ensuring that...

Characterizations of p-Parabolicity on Graphs

Florian Fischer

We study p-energy functionals on infinite locally summable graphs for \(p \in (1,\infty) \) and discuss that many well-known characterizations for a parabolic space are also true in this discrete,...

Static and Stationary Vacuum Extensions Realizing Bartnik Boundary Data: Local Well-Posedness near Schwarzschild Spheres

Ahmed Ellithy

We consider the Bartnik extension problem, which originates from Bartink's definition of quasi-local mass. In this problem, we consider Bartnik boundary data on a topological 2-sphere (induced metric...
