Non-local composite spin-lattice polarons in high temperature superconductors
G. De Filippis, V. Cataudella, A. S. Mishchenko +1
The non-local nature of the polaron formation in t-t'-t"-J model is studied in large lattices up to 64 sites by developing a new numerical method. We show that the effect of longer…

On the validity of the Franck-Condon principle in the optical spectroscopy: optical conductivity of the Fröhlich polaron
G. De Filippis, V. Cataudella, A. S. Mishchenko +2
The optical absorption of the Fröhlich polaron model is obtained by an approximation-free Diagrammatic Monte Carlo method and compared with two new approximate approaches that trea…
