Query: Non-equilibrium relaxation of a trapped particle in a near-critical
  Gaussian field   We study the non-equilibrium relaxational dynamics of a probe particle
linearly coupled to a thermally fluctuating scalar field and subject to a
harmonic potential, which provides a cartoon for an optically trapped colloid
immersed in a fluid close to its bulk critical point. The average position of
the particle initially displaced from the position of mechanical equilibrium is
shown to feature long-time algebraic tails as the critical point of the field
is approached, the universal exponents of which are determined in arbitrary
spatial dimensions. As expected, this behavior cannot be captured by adiabatic
approaches which assume fast field relaxation. The predictions of the analytic,
perturbative approach are qualitatively confirmed by numerical simulations.
