The robustness of quantum electrical current magnification in the face of thermodynamical decoherence is studied. Thermodynamical calculations for the specific heat, internal energy and electrical current suggest that magnification is decimated by temperature. The range of validity of the phenomenon is at order of the equivalent spectral band. With respect to the Milburn theory of decoherence, electrical current magnification is robust. Moreover, magnification phenomenon is widely exhibited in a large variety of quantum circuits and a wide variety of experimental setups can be envisaged.

The isothermal explosion model of Korobeinikov has been generalized to include the specific heat varying as temperature to the power k. Unlike Korobeinikov the different phases of the motion arc considered. The eventual self-similar solutions only exist for k > −1/2 and resemble that for k = 0 (the Korobeinikov value). For all k ≥ 0 the limiting expansion velocity is given by the von Neumann–Taylor–Sedov result (independent of k) and for k > 0 the internal energy decreases steadily. For k > 1/2 there is first an intermediate detonation phase. For −1/2 < k < 0 the kinetic energy first increases, then decreases, and the expansion law depends on k.
