Within a non-adiabatic dynamical method, we simulate charged polaron motion and dissociation in an organic molecule in the presence of dissipation. The dissipation, represented by damping, is introduced to investigate the influence of temperature on the mobility of carriers. We find that the velocity of the polaron has an inversely linear dependence on the damping, and hence the relationship be...

Effects of interchain interaction on the polaron-bipolaron transition on conjugated polymer are investigated. We use the Su-Schrieffer-Heeger model combined with the Pariser-Parr-Pople model modified to include interchain interaction, and an external electric field. We study the dynamics within the Time-Dependent Unrestricted HartreeFock approximation. We find that removing an electron from int...

Abstract We investigate the polaronic properties of a single impurity immersed in weakly interacting bosonic environment confined within one-dimensional double-well potential using an exact diagonalization approach. find that increase impurity-bath coupling results vanishing residue, signifying occurrence polaron orthogonality catastrophe. Asymptotic configurations systems' ground state wave fu...

We present a theory for spin-polarized transport through a generic organic polymer connected to ferromagnetic leads with arbitrary angle θ between their magnetization directions, taking into account the polaron and bipolaron states as effective charge and spin carriers. Within a diffusive description of polaron-bipolaron transport including polaron-bipolaron conversion, we find that the bipolar...

As is generally known, the polaron concept was introduced by Landau in 1933 [1]. Gradually a distinction was made between polarons in the continuum approximation where long-range electron-lattice interaction prevails (“Fröhlich”polarons) and polarons for which the short-range interaction is essential (Holstein, Holstein-Hubbard models). After a period of initial theoretical [1, 2, 3, 4, 5, 6, 7...

We study the Bose polaron problem in a nonequilibrium setting, by considering an impurity embedded quantum fluid of light realized exciton-polaritons microcavity, subject to coherent drive and dissipation on account pump cavity losses. obtain effective mass, drag force acting impurity, determine trajectories at semiclassical level. find different dynamical regimes, originating from unique featu...

The phonon spectral function of the one-dimensional Holstein model is obtained within weak and strong-coupling approximations based on analytical self-energy calculations. The characteristic excitations found in the limit of small charge-carrier density are related to the known (electronic) spectral properties of Holstein polarons such as the polaron band dispersion. Particular emphasis is laid...
