Non-uniform superconducting phases generated by spin-orbit interaction — •Julie Baumard^{1, 2}, Jerome Cayssol¹, and Alexandre Buzdin¹ — ¹LOMA - UMR 5798, Bordeaux, France — ²DIPC, Donostia-San Sebastián, Spain

Non-uniform superconducting states raise great interest in the scientific community. One of the most famous is the FFLO state, predicted in the 1960's. It is characterized by a higher critical field than the uniform superconducting state. The FFLO state appears at low critical temperature, which makes it difficult to observe experimentally. In this presentation, we will show that adding spin-orbit interaction allows the modulated phase to appear at high critical temperature.The system studied consists of a superconducting nanowire with Zeeman field and Rashba spin-orbit interaction.
