Minkowski metric signature as a statistical prediction of piecewise-flat quantum gravity
Mihailo Djordjevic, Igor Prlina, Marko Vojinovic
We study an ab initio calculation of the signature of the spacetime metric, within the framework of piecewise-flat models of quantum gravity. Applying numerical techniques, we eval…

Detecting Hidden Nonlinear High Frequency Modes Beyond Fundamental Minimal Temporal Resolution Using Weak Measurements
Igor Prlina
In this work we study whether nonlinear models of quantum mechanics can avoid detection by strong measurements, if the nonlinear effects only exist as high frequency modes. A poten…

If Quantum Measurements Are Secretly Continuous Nonunitary Processes, Weak Measurements Can Detect It
Igor Prlina, Milutin Živković
The standard approach to quantum measurements is to assume that they lead to effectively instantaneous collapse of the quantum state. However, if we assume that we are unable to en…
