This study introduces a stochastic growth model controlled by temperature (T). It reveals distinct dynamical behaviors, including transitions between quenched Kardar-Parisi-Zhang (KPZ) and Edwards-Wilkinson (EW) universality classes as T varies.

Area of Science:

  • Statistical Physics
  • Nonlinear Dynamics
  • Surface Growth Phenomena

Background:

  • Stochastic growth models are crucial for understanding various physical phenomena.
  • The Kardar-Parisi-Zhang (KPZ) and Edwards-Wilkinson (EW) universality classes describe different surface growth dynamics.
  • Understanding crossovers between these classes is essential for a complete picture.

Purpose of the Study:

  • To introduce and analyze a novel stochastic growth model controlled by a temperature-like parameter (T).
  • To investigate the dynamical behavior and universality classes of the model across a range of T values.
  • To explore the anomalous crossover behavior between quenched KPZ and thermal KPZ classes.

Main Methods:

  • Development of a stochastic growth model with a temperature-like parameter (T).

  • Investigation of anisotropic effects of quenched noise and scaling behavior of interface width.

    • Main Results:

    • The model exhibits distinct behaviors corresponding to quenched KPZ (T=0) and EW (T=infinity) universality classes.
    • An anomalous crossover from quenched KPZ to thermal KPZ is observed for intermediate T values.
    • KPZ nonlinearity arises from anisotropic quenched noise, present only for finite T.

    Conclusions:

    • The introduced model provides a unified framework to study transitions between different universality classes in surface growth.
    • The temperature parameter (T) effectively controls the crossover dynamics and the nature of the growth process.
    • The findings offer new insights into the role of noise anisotropy in generating nonlinear growth dynamics.
