The magnon-mediated attraction between two holes doped in a CuO layer
Mirko M. Moeller, Clemens P. J. Adolphs, Mona Berciu
Using a realistic multi-band model for two holes doped into a CuO layer, we devise a method to turn off the magnon-mediated interaction between the holes. This allows us to ver…
Phonon-mediated repulsion, sharp transitions and (quasi)self-trapping in the extended Peierls-Hubbard model
J. Sous, M. Chakraborty, C. P. J. Adolphs +2
We study two identical fermions, or two hard-core bosons, in an infinite chain and coupled to phonons by interactions that modulate their hopping as described by the Peierls/Su-Sch…
Non-Zhang-Rice singlet character of the first ionization state of T-CuO
Clemens P J Adolphs, Simon Moser, George A Sawatzky +1
We argue that tetragonal CuO (T-CuO) has the potential to finally settle long-standing modelling issues for cuprate physics. We compare the one-hole quasiparticle (qp) dispersion o…
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…
