Evidence of Andreev bound states as a hallmark of the FFLO phase in -(BEDT-TTF)Cu(NCS)
H. Mayaffre, S. Kramer, M. Horvatić +4
Superconductivity is a quantum phenomena arising, in its simplest form, from pairing of fermions with opposite spin into a state with zero net momentum. Whether superconductivity c…
Quantum oscillations and upper critical magnetic field of the iron-based superconductor FeSe
