Towards the parameterisation of the Hubbard model for salts of BEDT-TTF: A density functional study of isolated molecules
Edan Scriven, B. J. Powell
We calculate the effective Coulomb repulsion between electrons/holes, U, and site energy for an isolated BEDT-TTF [bis(ethylenedithio)tetrathiafulvalene] molecule in vacuo. U=4.2 \…
Preparation of Metal Mixed Plastic Superconductors: Electrical Properties of Tin-Antimony Thin Films on Plastic Substrates
Andrew P. Stephenson, Ujjual Divakar, Adam P. Micolich +2
Metal mixed polymers are a cheap and effective way to produce flexible metals and superconductors. As part of an on-going effort to learn how to tune the properties of these system…
Vertex Corrections and the Korringa Ratio in Strongly Correlated Electron Materials
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We show that the Korringa ratio, associated with nuclear magnetic resonance in metals, is unity if vertex corrections for the dynamic spin susceptibility are negligible and the hyp…
Unified explanation of the Kadowaki-Woods ratio in strongly correlated materials
A. C. Jacko, J. O. Fjaerestad, B. J. Powell
Discoveries of ratios whose values are constant within broad classes of materials have led to many deep physical insights. The Kadowaki-Woods ratio (KWR) compares the temperature d…
