1.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反节点子遭受到额外的强散射, 可能与费米面的拓扑行为有关。
2.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.
