It was also found that antinodal electrons in underdoped LSCO experience some extra strong scattering process, which may be related to the Fermi surface topology.
并且发现欠掺杂LSCO反节点电子遭受到额外的强散射过程, 这可能与米面的拓扑行为有关。
A Feynman propagator is constructed for the effective interaction between electrons which takes into account the polarizability of the medium of unexcited particles in the Fermi sea.
