Author(s): Yu Zhang, Yuan-Pei Yang, and Liang-Liang Ji Relativistic magnetized shocks are natural sources of coherent radiation, representing a promising framework for fast radio bursts (FRBs). This Letter explores how the radiation reaction (RR) effect, triggered by high-energy photon emissions during shock radiation, significantly alters particle dyna… [Phys. Rev.
