WebThe meaning of FRÖHLICH is joyous, happy—used as a direction in music. WebMay 11, 2024 · In this paper, we show that Fröhlich theory can be extended to eliminate this problem. We derive four additional terms in the Fröhlich Hamiltonian to account for anharmonicity up to third order. We calculate the energy and effective mass of the new polaron, using both perturbation theory and Feynman's path-integral formalism.
