Electron-vibron interactions can lead to the formation of coupled breathers. These localized excitations facilitate energy transfer and influence relaxation dynamics in lattice systems.

Area of Science:

  • Condensed Matter Physics
  • Nonlinear Dynamics
  • Quantum Chemistry

Background:

  • The study of localized excitations, such as solitons and breathers, is crucial in understanding energy transport and dynamics in various physical systems.
  • Coupled electron-vibron systems are fundamental models for describing phenomena in molecular crystals, organic conductors, and other condensed matter systems.

Purpose of the Study:

  • To investigate the dynamics and interaction of electronic and vibronic breathers in a coupled electron-vibron lattice system.
  • To analyze the energy exchange mechanisms between electronic and vibronic subsystems and their influence on breather formation and stability.
  • To understand the role of breathers in the relaxation dynamics of nonequilibrium systems.

Main Methods:

  • Numerical simulations of the coupled electron-vibron lattice dynamics.

  • Linear stability analysis to determine the stability of localized modes and energy transfer roles.
  • Frequency analysis to identify transitions in breather dynamics (e.g., single- to two-frequency oscillations).

    • Main Results:

    • Coexistence of electronic and vibronic breathers is demonstrated under specific conditions.
    • Energy transfer predominantly flows from the electronic to the vibronic subsystem, facilitating relaxation.
    • Breathers significantly impact relaxation dynamics, often accelerating the process.
    • A transition from single-frequency to two-frequency breathers and their resonant interactions were observed.
    • Under strong coupling, a large-amplitude vibronic phonobreather survives, while electronic energy equilibrates.

    Conclusions:

    • Breathers play a vital role in mediating energy exchange and relaxation in coupled electron-vibron systems.
    • The electronic subsystem acts as an energy donor, while the vibronic subsystem acts as an energy acceptor.
    • The system dynamics evolve towards a stable state, characterized by combined electron-vibron breathers or vibronic phonobreathers depending on coupling strength.
