We consider how electron-phonon interaction influences the insulator-metal transitions driven by doping in a strongly correlated system. Using polaronic version of generalized tight-binding method, we investigate multiband two-dimensional model taking into account both charge density displacement and transitive types electron-lattice contributions. For adiabatic ratio $t\ensuremath{\gg}{\ensure...

We unravel the polaronic properties of impurities immersed in a correlated trapped one-dimensional (1D) Bose-Bose mixture. This setup allows for to couple either attractively or repulsively specific host, thus offering highly flexible platform steering emergent properties. Specifically, residue peak and strength induced interactions can be controlled by varying coupling individual bosonic compo...

Polarons originating from phonon displacement modulated hopping have relatively light masses and, thus, are of significant current interest as candidates for bipolaron mechanism high-temperature superconductivity [Phys. Rev. Lett. {\bf 121}, 247001 (2018)]. We observe that the bond model, when dominant coupling comes atomic vibrations on lattice bonds, can be solved by efficient sign-free Monte...
