    • Note that in equilibrium thermodynamics, people frequently distinguish functions of a quasiequilibrium thermodynamical process (the one which can be viewed as a chain of equilibrium states) from functions of the state. In this context, the change in heat is written as dQ. Here we consider (possibly strongly) nonequilibrium situations, where almost any quantity (e.g., energy) is a function of the process. Therefore, we do not introduce the symbol d.

    • note
    • Here and after, we do not present the results of the full optimization of the work over the parameters of the involved pulses. The reason is that we do not want to make the pulsing setup too dependent on the details of the model. On the other hand, the results of this full optimization did not show any qualitative difference with the presented ones.

    • note
    • It is known in the literature that one can obtain decoupling of the spin from the means of strong pulses [22,34]. However, recently the restriction of sharp pulses was relaxed while still sucesfully achieving dynamical decoupling [61]. This prompts a hope that also for the present effect the strong and sharp pulse restriction is not necessary.
