Positive and inverse isotope effect on superconductivity
Tian De Cao
This article improves the BCS theory to include the inverse isotope effect on superconductivity. An affective model can be deduced from the model including electron-phonon interact…
Multiferroics seen from theoretic derivation of a tight binding model
Tian De Cao
One presented some lattice models, while the theoretic derivation has not been found, and the importance of correlation effects has to be emphasized. On the basis of the non-relati…
Pseudogap associated with precursor pairing
Tian De Cao
This work argues that the off-diagonal long range order (ODLRO) is not necessary for showing superconductivity while the electron pairing around Fermi surface is sufficient for sup…
High temperature superconductivity in metallic region near Mott transition
Tian De Cao
The spin-singlet superconductivity without phonons is examined in consideration of correlations on an extended Hubbard model. It is shown that the superconductivity requires not on…
A new model and its physics
Tian De Cao
The high temperature superconductivity in cuprate materials1 has puzzled scientists over twenty years. We must find a new way to understand superconductivity. It is found the spin-…
High-Tc superconductivity originated from strong spin-charge correlation: indication from linear temperature dependence of resistivity
Tian De Cao
Both the highest- and the linear temperature dependence of the resistivity in wide temperature range appear at the optimally doped regions of Cu-based superconductors1,2,3,4,5, and…
