Paramagnetic Meissner, vortex and 'onion' ground states in Fulde-Ferrell finite-size superconductor

V. D. Plastovets, D. Yu. Vodolazov

We theoretically find that finite size Fulde-Ferrell (FF) superconductor (which is characterized by spatially nonuniform ground state $\Psi \sim \text{exp}(-i{\mathbf{q}}_{FF}\mathbf{r})$ and…
