    "abstract": "We present a stochastic theory of charges moving in an electromagnetic field\nusing nonequilibrium quantum field theory. We give a first principles\u0027\nderivation of the Abraham-Lorentz-Dirac-Langevin equation which depicts the\nquantum expectation value for a particle\u0027s trajectory and its stochastic\nfluctuations by combining the worldline path integral quantization with the\nFeynman-Vernon influence functional or closed-time-path effective action\nmethods. At lowest order, the equations of motion are approximated by a\nstochastic Lorentz-Dirac equation.",
