Following the Dirac-Frenkel time-dependent variational principle, dynamics of a one-dimensional Holstein polaron with off-diagonal exciton-phonon coupling is probed by employing the Davy dov D2 Ansatz with two sets of variational parameters,one for each constituting particle in the exciton-phonon sy...
