Comparison of the Electronic Structures and Energetics of Ferroelectric LiNbO3 and LiTaO3
Iris Inbar, R. E. Cohen
This paper explains the origin of the ferroelectric instability in LiNbO3 and LiTaO3 and compares the electronic structures and energetics of the two materials.
Insulator-metal transition in solid hydrogen: Implication of electronic structure calculations for recent experiments
I. I. Mazin, Ronald E. Cohen
Electronic structure calculations for compressed molecular hydrogen are performed to provide more insight into the diversity of phenomena recently observed experimentally. We perfo…
"Chain scenario" for Josephson tunneling with pi-shift in YBa2Cu3O7
I. I. Mazin, A. A. Golubov, A. D. Zaikin
We point out that all current Josephson-junction experiments probing directly the symmetry of the superconducting state in YBa2Cu3O7, can be interpreted in terms of the bilayer ant…
High Pressure Effects on Thermal Properties of MgO
Iris Inbar, R. E. Cohen
Using the non-empirical Variational Induced Breathing (VIB) model, the thermal properties of periclase (MgO) under high pressures and temperatures are investigated using molecular…
Neutron scattering and superconducting order parameter in YBa2Cu3O7
I. I. Mazin, Victor M. Yakovenko
We discuss the origin of the neutron scattering peak at 41 meV observed in YBaCuO below . The peak may occur due to spin-flip electron excitations across the super…
s-wave superconductivity from antiferromagnetic spin-fluctuation model for bilayer materials
A. I. Liechtenstein, I. I. Mazin, O. K. Andersen
It is usually believed that the spin-fluctuation mechanism for high-temperature superconductivity results in d-wave pairing, and that it is destructive for the conventional phonon-…
