Such an effect is closely associated with the topology of the Hamiltonian describing Sr 2 RuO 4 in the superconducting state, which is characterized by a nonzero Chern number.

It shows that the superconducting state does not depend on the history of preparation, only upon the present values of temperature, pressure and magnetic field, and therefore is a true thermodynamic state.
13.
This modest coherence length means that the superconducting state is more susceptible to local disruptions from interfaces or defects on the order of a single unit cell, such as the boundary between twinned crystal domains.
14.
The entropy change is small, this must mean that only a very small fraction of electrons participate in the transition to the superconducting state but, the electronic contribution to the heat capacity changes drastically.
15.
As long as the induced magnetic field at the edges is less than the critical field, the material remains superconducting, but at higher currents the field becomes too strong and the superconducting state is lost.
16.
Moreover, it has been theoretically shown that RIXS can probe Bogoliubov quasiparticles in high-temperature superconductors, and shed light on the nature and symmetry of the electron-electron pairing of the superconducting state.
17.
In the first years after the discovery of UPd 2 Al 3 it was actively discussed whether its superconducting state can support a Fulde Ferrell Larkin Ovchinnikov ( FFLO ) phase, but this suggestion was later refuted.
18.
In the superconducting state, each term of the Hamiltonian is dependent, because of the superconducting state consists of a phase-coherent superposition of occupied one-electron states, whereas it is independent in the normal state.

20.
As the magnetic field increases, the flux cylinders move closer together and eventually at the upper critical field H _ { c2 }, they leave no room for the superconducting state and the zero-conductivity property is lost.
