Atomic clocks and gravitational waves as probes of non-metricity

Abstract Non-metricity provides a natural extension of Riemannian geometry, yet its experimental signatures remain largely unexplored. In this work we investigate how spacetime non-metricity can be probed through high-precision observations, focusing on atomic clocks and gravitat...

Computational Reanalysis of Optical Mode Localization in Fiber-Coupled Ring Resonators Using Temperature-Dependent Temporal Coupled-Mode Theory

This preprint presents a computational reanalysis of optical mode localization in fiber-coupled ring resonators using a temperature-dependent Temporal Coupled-Mode Theory (TCMT) framework. The study investigates publicly available experimental transmission spectra from weakly cou...

A winding number analysis of Schwarzschild black hole stability in light of Planck-scale modified kinematics

Abstract Determining whether Planck-scale effects can stabilize black holes addresses fundamental questions about black hole evaporation and quantum gravity consistency. Here, we analyze the thermodynamic topology ofSchwarzschild black holes under Planck-scale modified kinematics...
