  • We examine the emergence of periodicity in a non-interacting steady-state quantum system without external drive inspired by quantum time crystals' spontaneous time-translation symmetry breaking. Specifically, we consider a lattice ring of non-interacting electrons undergoing weak local position measurements. Our analysis uncovers time-periodic structures in steady-state two-time correlation functions, with periodicity linked to the system's group velocity. This study demonstrates a measurement-induced clock mechanism, highlighting periodic behaviors in two-time correlators of a non-equilibrium steady state, contributing to understanding time-periodic phenomena in minimally interactive quantum systems.
