The authors describe a variational approach for solving the Holstein polaron model with dynamical quantum phonons on an infinite lattice. The method is simple, fast, extremely accurate, and gives ground and excited state energies and wavefunctions at any momentum k.

The excited state condensation in lattices results from the interplay of gain-relaxation dynamics and the finite lifetime of the polaritons, making it more favourable to condense in these by:   Book Search tips Selecting this option will search all publications across the Scitation platform Selecting this option will search all Direct evidence for degradation of polaron excited states in organic light emitting diodes Journal of Applied We find that the mCBP anion is unstable and becomes more so in its excited by: condensed state even at room temperature.

That is not an idle dream. Condensed-matter physicists have a long history of inventing novel quasiparticles, such as mass-less electrons, particles with fractional charge, and particles with spins detached from their charges.

Two decades ago re-searchers began to engineer hybrid particles of light and. Many condensed matter problems involve a particle coupled to its environment. The polaron, originally introduced to describe electrons in a polarizable medium, describes a particle coupled to a bosonic field.

The Holstein polaron model, although simple, including only optical Einstein phonons and an interaction that couples them to the electron density, captures almost all of the standard. The coupling between an electronic system and an environmental bath plays a decisive role in the excited state dynamics of artificialnatural molecular condensed phases.

Although it is generally difficult to control the coupling between the system and the thermal bath in condensed matter, a strong lightmatter coupling can control systembath coupling properties using the polaron.

Excited polaron states in condensed media. The electronlattice interaction is then introduced as a dynamical response of condensed matter when it is electronically excited. With the aid of proper configuration coordinate diagrams, various phenomena are precisely examined, including carrier scattering, polaron formation, lattice relaxation, Stokes shift and phonon side band in optical.

Book description. High-temperature superconductivity has transformed the landscape of solid state science, leading to the discovery of new classes of materials, states of matter, and concepts. However, despite being over a quarter of a century since its discovery, there is still no single accepted theory to explain its origin.

The polaron concept was introduced by Landau in The physical properties of the polaron differ from those of the band carrier. In particular, the polaron is characterized by its binding (or self-) energy E 0, effective mass m and by its response to external electric and magnetic fields (e.dc mobility and optical absorption coefficient).

Indeed, coincides with the second order contribution to the ground state energy of the Bose polaron obtained in [21, 24] in the limit of a zero range potential with. Comparing with the limit given by, we see that the integral determines the dynamical formation of the polaron state.

The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and interacting with a many-body background. We discuss the impact of the impurities on the medium particles by considering feedback effects from polarons that can be realized in ultracold quantum gas experiments.

[4][5][6] The excited state formation kinetics can be approximated at a lattice temperature of K as previously done for hematite at a similar excitation power density as used here.

LiNbO 3-type crystals have long-lived excited states called polarons, which have large absorption cross sections for visible and infrared light with values in the order of cm 2.

To evaluate the nonlinear absorption power density, we use a rate-equation model for the conduction-band electrons and polarons under laser irradiation. The superexchange through virtual phonons in the dynamics of elementary electron transfer from excited electronic states of aggregated molecules February Journal of Luminescence A general scheme is presented that illustrates, in a most simple MO scheme, the mode of excitation energy and electron transfer from an electronically excited to a ground state pigment molecule.

These two types of processes are the elementary steps of light harvesting by the antenna and charge separation in the reaction centers.

The lifetime of singlet excitons in conjugated polymer films is a key factor taken into account during organic solar cell device optimization. It determines the singlet exciton diffusion lengths in polymer films and has a direct impact on the photocurrent generation by organic solar cell devices.

However, very little is known about the material properties controlling the lifetimes of singlet. Given the success of the polaron model based on solvation in accounting for the width of a hole polaron on an all-adenine (A) sequence on DNA, we extend the calculations to other sequences.

We find excellent agreement with the free energy differences measured by Lewis et al. Chem. Soc., ) between a guanine (G) cation and a pair of bases, GG, or a triple of.

Comparison with discrete model. Earlier we considered the problem of symmetry breakdown for one electron interacting with oscillations of a one-dimensional quantum chain (Lakhno ). According to Lakhno (), a rigorous quantum-mechanical treatment leads to delocalized translation-invariant electron states, or to a lack of soliton-type solutions, breaking the initial symmetry of the.

CT models with localized trapping states can mimic the polaron effe which would increase the computed resistance in even-length sequences. However, models that capture polaron.

Charge migration through DNA has been the focus of considerable interest in recent years. A deeper understanding of the nature of charge transfer and transport along the double helix is important in fields as diverse as physics, chemistry and nanotechnology.

It has also important implications in biology, in particular in DNA damage and repair. 15(1). Nature Physics 8, ().

On June, the Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine in Lviv hosted the XVIII Workshop and Award for young researchers in the field of statistical physics and condensed matter theory, which was organized by the Lviv Young Minds Section and supported by the EPS Young Minds Committee.

The density of states function g(E) is defined as the number of electronic states per unit volume, per unit energy, for electron energies near E. The density of states function is important for calculations of effects based on band theory.

In Fermi's Golden Rule, a calculation for the rate of optical absorption, it provides both the number of excitable electrons and the number of final states.

A unifying element that links the apparently diverse phenomena observed in optical processes is the dielectric dispersion of matter. It describes the response of matter to incoming electromagnetic waves and charged particles, and thus predicts their behavior in the self-induced field of matter.

This book provides an attempt to convey the colorful facets of condensed matter systems with reduced dimensionality. Some of the specific features predicted for interacting one-dimensional electron systems, such as charge- and spin-density waves, have been observed in many quasi-one-dimensional materials.
