Abstract
We study AB oscillations of transition temperature,
paraconductivity and specific heat of thin ring in the regime of
inhomogeneous Larkin- Ovchinnikov- Fulde- Ferrell (LOFF)
superconducting state. We found that in contrast to uniform
superconductivity magnetic flux might increase the critical
temperature of LOFF state. Degeneracy of the inhomogeneous
superconducting state reveals in double peak structure of AB
oscillations.
