摘要: An anharmonic electron phonon interaction model is used to study lattice and electronic effects of high-temperature superconductors (HTSC). Due higher-order densitymultiphonon interactions the effective electron-phonon coupling experiences a strongq-dependence which leads incommensurations, stripes, tweeds in dynamical ionic displacement pattern. Simultaneously these terms induce strong interband enhance intraband electron-hole pair formation contribute substantially high superconducting transition temperaturesT c . The resulting gap structure highly anisotropic. using its energy-dependent experimentally observed electromagnetic response calculated well reproduced.
