Query: Self-Force with a Stochastic Component from Radiation Reaction of a
  Scalar Charge Moving in Curved Spacetime   We give a quantum field theoretical derivation of the scalar
Abraham-Lorentz-Dirac (ALD) equation and the self-force for a scalar charged
particle interacting with a quantum scalar field in curved spacetime. We
regularize the causal Green's function using a quasi-local expansion in the
spirit of effective field theory and obtain a regular expression for the
self-force. The scalar ALD equation obtained in this way for the classical
motion of the particle checks with the equation obtained by Quinn earlier
\cite{Quinn}. We further derive a scalar ALD-Langevin equation with a classical
stochastic force accounting for the effect of quantum fluctuations in the
field, which causes small fluctuations on the particle trajectory. This
equation will be useful for the study of stochastic motion of charges under the
influence of both quantum and classical noise sources, derived either
self-consistently (as done here) or put in by hand (with warnings). We show the
possibility of secular effects from such stochastic influences on the
trajectory that may impact on the present calculations of gravitational
waveform templates.
