WebJun 30, 2024 · the Frohlich Hamiltonian for the bipolaron. The last term in the Hamiltonian (1) describes the interaction of the charge carriers with the polarization field induced by the optical vibrations of the crystal lattice. The interaction amplitude (2) results from a Fourier transform of the electrondipole interaction potential. WebFollowing the ideas behind the Feynman approach, a variational wave function is proposed for the Fröhlich model. It is shown that it provides, for any value of the electron-phonon …

WebApr 14, 2024 · We know (I think) that for a given Hamiltonian the minimum eigenvalue is associated with the ground state. But if we take the Hamiltonian to be Pauli Z, then it has two eigenvalues: 1 associated with state 0 and -1 associated with state 1 . Clearly the minimum eigenvalue is -1 so the ground state should be 1 . WebOct 9, 2024 · In this paper, a method based upon Hamilton's integral variational principle is developed to determine invariants for non-conservative dynamical system (Equation … tote enterprises clearwater fl
