    • note
    • The approach of van Zon and Cohen to the calculation of P (Q, t) is based on the integration of a work distribution function, P (W, t), over all values of W under an energy conservation (first law) constraint. P (W, t) is a Gaussian when v, the speed of the trap, is nonzero. However, when v = 0 (the limit of interest for our calculations), no work is done, and the work distribution is a delta function, δ (W). Integration over W now merely equates Q to the net energy change, without determining its distribution at all; an average over the stochastic trajectories of the particle and its initial distribution must be carried out to obtain P (Q, t).

    • on the thermodynamics of a colloidal particle trapped in a bistable potential and modulated by an external periodic force, exact heat and work distributions were calculated, but only by numerical solution of a Fokker-Plank equation, followed by numerical inversion of a Fourier transform; closed-form expressions were not derived. Fluctuations in the heat and work were also probed in a study by [10.1103/PhysRevLett.96.070603on the dynamics of a colloidal particle trapped in a time-dependent nonharmonic potential, but no closed-form expressions for the associated heat distribution were derived here either.
