We develop a theory of inherent non-thermal superconducting electronic instabilities.
Significance and Impact
Our result provides key insights into the origin of switching voltage instabilities in superconductors.
- A theory is constructed in the framework of the time-dependent Ginzburg-Landau equation.
- The S-shape of the I-V curves is generated by superconducting fluctuations.
- In 2D superconductors, the Berezinskii-Kosterlitz-Thouless transition is accompanied – and can be identified – by the voltage switching jumps.
