Pressure-driven phase transitions in correlated systems
Yu-Zhong Zhang, Ingo Opahle, Harald O. Jeschke +1
Motivated by recent experimental measurements on pressure-driven phase transitions in Mott-insulators as well as the new iron pnictide superconductors, we show that first principle…
First principles determination of the model parameters in -(ET)Cu(CN)
Harald O. Jeschke, Hem C. Kandpal, Ingo Opahle +2
We present a detailed study of the derivation of the Hubbard model parameters for -(ET)Cu(CN) in the framework of {\it ab initio} Density Functional Theory. We show…
Tuning of crystal structure and magnetic properties by exceptionally large epitaxial strains
J. Buschbeck, I. Opahle, M. Richter +7
Huge deformations of the crystal lattice can be achieved in materials with inherent structural instability by epitaxial straining. By coherent growth on seven different substrates…
Revision of model parameters for kappa-type charge transfer salts: an ab initio study
Hem C. Kandpal, Ingo Opahle, Yu-Zhong Zhang +2
Intense experimental and theoretical studies have demonstrated that the anisotropic triangular lattice as realized in the kappa-(BEDT-TTF)2X family of organic charge transfer (CT)…
The electronic structure of CeCoIn5 from angle-resolved photoemission spectroscopy I: Comparison to LDA
A. Koitzsch, I. Opahle, S. Elgazzar +12
We have investigated the low-energy electronic structure of the heavy fermion superconductor CeCoIn5 by angle-resolved photoemission and band structure calculations. We measured th…
