摘要：The robustness of the macroscopic quantum nature of a superconductor can be characterized by the superfluid stiffness, rho s, a quantity that describes the energy required to vary the phase of the macroscopic quantum wavefunction. In unconventional superconductors, such as cuprates, the low-temperature behaviour of rho s markedly differs from that of conventional superconductors owing to quasiparticle excitations from gapless points (nodes) in momentum space. Intensive research on the recently...
