BCS theory models Type I materials with this property.
This property's emergence can be modeled by a second-order phase transition with an order parameter proportional to the attractive potential between electrons. This property, which has characteristic lengths called the penetration depth and coherence length, can be understood as the condensation of Cooper pairs. Some materials with this property are perfect diamagnets that expel internal magnetic fields via the Meissner effect. BCS theory models Type I materials with this property. For 10 points, name this property in which materials have zero electrical resistance.
This property's emergence can be modeled by a second-order phase transition with an order parameter proportional to the attractive potential between electrons.
