Superconducting diode effect in fractal superconductors: fractional-order Ginzburg-Landau theory for Josephson junctions

Yuriy Yerin, Iman Askerzade

We develop a fractional-order Ginzburg-Landau (GL) framework for nonreciprocal superconducting transport in Josephson junctions formed by fractal superconductors or superconducting…
