The Mechanism for High Temperature Superconductivity
Abstract
The emergence of FeSC drives the physics community to hot debate, bringing more confusion and new opportunities to the research in high temperature superconductivity. We start with the conventional theory and its hint for high temperature superconductors. The hopping and exchange interaction for the effective model are derived. From the effective exchange, an unification theory for the magnetism in FeSC is explored. Specially, the spin wave theory and its Higgs mode are studied in detail, as an interpretation of the observed gapped excitation. The latest theory to unify the high Tc problem is given and the possible candidates for new class of HTSC are predicted. We wish this work ultimately to push the theory of HTSC to a new stage. Besides, the energy saving mechanism and some other miscellaneous topics are attached as a completion of this thesis.
