A Different Perspective on Superconductivity in Crystalline Graphene: Exploiting Energetics
The paper explains superconductivity in graphene by using a 'two-parent' energetic framework to resolve why it appears as narrow slivers near boundaries between different metal states. It shows that a first-order transition between two normal isospin states allows the superconducting gain to be decisive, leading to specific confinement patterns and explaining experimental observations.
