Theory of angle-resolved photoemission experiments on a two-band model
Tian De Cao
Considering the electron states inside and outside the solid, we derive a formula of photoemission intensity. A general theoretical way to determine electronic structures of solids…
Prerequisite for superconductivity: appropriate spin-charge correlations
Tian De Cao
This work investigates the relation between superconductivity and correlations. A simple calculation shows that the appropriate spin-charge correlation is the key role to any super…
Basic physics of solid materials
Tian De Cao
Since the cuprate materials behave many curious properties, the mechanism that causes high-temperature superconductivity in copper oxide materials (cuprates) has been a controversi…
Pairing with non-opposite momentum in superconductors
Tian De Cao
The basic feature of the BCS theory is that pairing occurs between electrons in states with opposite momentum and opposite spins, e.g., between states (k) and (-k), in which the sy…
What is the highest Tc for phonon mediated superconductivity?
Tian De Cao
We suggest that the high-temperature superconductivity is attributed to the director-roles of van Hove singularity between electron-electron interaction and electron-phonon interac…
