Nucleation of superconductivity under rapid cycling of electric field
@article{Bandyopadhyay2008NucleationOS, title={Nucleation of superconductivity under rapid cycling of electric field}, author={Malay Bandyopadhyay}, journal={arXiv: Superconductivity}, year={2008} }
The effect of an externally applied high frequency oscillating electric field on the critical nucleation field of superconductivity in the bulk as well as at the surface of a superconductor is investigated in details in this work. Starting from the linearized time dependent Ginzburg-Landau (TDLG) theory and using the variational principle we have shown the analogy between a quantum harmonic oscillator with that of the nucleation of superconductivity in bulk and a quantum double oscillator with…
