Band structure of the Jahn-Teller polaron from Quantum Monte Carlo
P. E. Kornilovitch
A path-integral representation is constructed for the Jahn-Teller polaron (JTP). It leads to a perturbation series that can be summed exactly by the diagrammatic Quantum Monte Carl…

Ground-state dispersion and density of states from path-integral Monte Carlo. Application to the lattice polaron
P. E. Kornilovitch
A formula is derived that relates the ground-state dispersion of a many-body system with the end-to-end distribution of paths with open boundary conditions in imaginary time. The f…

Giant enhancement of anisotropy by electron-phonon interaction
P E Kornilovitch
Anisotropic electron-phonon interaction is shown to lead to the anisotropic polaron effect. The resulting anisotropy of the polaron band is an exponential function of the electron-…
