Graceli categorical entropic quantum reversibility in superconductivity.

which shows that in certain situations there are reversible turns in transformations.

being also the breakdown of the superconducting state according to the categories and types of energies of Graceli, and changes of phases and potential of transitions of Graceli states.

the mercury superconductivity (Hg) at the helium (He) liquefaction temperature (~ 4.2 K). a superconducting material would return to its normal state, if through it passed a sufficiently high electric current. in which the breakdown of the superconducting state of Hg was due to the magnetic field associated with the electric current and not to the current itself.

following the general function of Graceli.
