The 18 pages that link to Fermi surface, each with the reason it gives.
FermionRelated: It organizes the low-energy behavior of many fermion systems.
BCS theoryRelated: The pairing instability acts most strongly on electrons near this boundary.
Brillouin zoneRelated: Its shape within the zone helps determine a metal's electronic properties.
Cooper pairRelated: Pairing is especially effective for electrons near this boundary.
Electron gasRelated: Its shape captures how electron states are filled in a material.
Leon CooperRelated: The Cooper instability arises from electrons near this boundary.
