Large electropositive cations as surfactants for the growth of polar epitaxial films
Alfred K. C. Cheung, Ilya Elfimov, Mona Berciu +1
Using density functional theory (DFT) we demonstrate that the adsorption of large cations such as potassium or cesium facilitates the epitaxial growth of polar LaAlO (LAO) on S…
Phonon-assisted carrier motion on the Wannier-Stark ladder
Alfred K. C. Cheung, Mona Berciu
It is well known that at zero temperature and in the absence of electron-phonon coupling, the presence of an electric field leads to localization of carriers residing in a single b…
The dynamics of a doped hole in cuprates is not controlled by spin fluctuations
Hadi Ebrahimnejad, George A. Sawatzky, Mona Berciu
Twenty seven years after the discovery of high-temperature superconductivity \cite{BedMu}, consensus on its theoretical explanation is still absent. To a good extent, this is due t…
Strongly bound yet light bipolarons for double-well electron-phonon coupling
Clemens PJ Adolphs, Mona Berciu
We use the Momentum Average approximation (MA) to study the ground-state properties of strongly bound bipolarons in the double-well electron-phonon (el-ph) coupling model, which de…
Single polaron properties for double-well electron-phonon coupling
Clemens P. J. Adolphs, Mona Berciu
We show that in crystals where light ions are symmetrically intercalated between heavy ions, the electron-phonon coupling for carriers located at the light sites cannot be describe…
