Acceleration deforms exponential decays into generalized Zipf-Mandelbrot laws

Publikacja

M. Czachor

- PHYSICS LETTERS A - Rok 2025

An exponentially decaying system looks as if its decay was a generalized power or double-exponential law, provided one takes into account the relativistic time dilation in a detector, the delay of the emitted signal, and the accelerations of both the source and the detector. The same mathematical formula can be found in generalizations of the Zipf-Mandelbrot law in quantitative linguistics and in the dynamics of ligand binding...
