The researchers focused on the Ising superconductor state, which has an extraordinary ability to resist magnetic fields that would normally disrupt superconductivity. They have successfully developed a device using bilayer molybdenum disulfide that can bridge Ising superconducting states within layers. This device essentially creates a superconducting transistor, allowing this protection to be activated or deactivated using an electric field.
The FFLO state that scientists have observed is a longstanding problem in the field of superconductivity. In this case, there is net kinetic momentum due to the small velocity difference between the electrons in the Cooper pairs. Previous attempts to create such a situation in conventional superconductors required extremely low temperatures and a strong magnetic field. However, in the Ising superconductor, Ye was able to reach the FFLO state using a weaker magnetic field and at higher temperatures.
More work needs to be done on this new superconducting state to better understand its properties and potential applications.
