The London equations can be used to describe the magnetic fields of these objects.
The London equations can be used to describe the magnetic fields of these objects. In a solid state, these materials come in LCO or YBCO forms. The London penetration depth, studied by John Schrieffer, is the depth a magnetic field penetrates these types of materials. According to BCS theory, below the Fermi level they form Cooper pairs through electron-phonon interactions. These objects expel their internal magnetic field by the Meissner effect. For 10 points, name these objects which have no electrical resistance.
