Author(s): Oded Farago We establish a mapping between one-dimensional run-and-tumble particle dynamics in the presence of thermal noise, and overdamped Brownian motion in a spatially inhomogeneous temperature field. The approach is formulated as an inverse-Clausius thermodynamic framework, where the effective temperature … [Phys. Rev. Lett. 137, 037103] Published Fri Jul 17, 2026
