Forced Oscillations

6.9K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Scaling

332
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Mechanical Systems

317
Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

Feedback control systems

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Summary

Coupling quenched disorders to driven models can lead to continuously varying universality classes. Scaling exponents depend on a disorder distribution parameter when the disorder is a relevant perturbation.

Area of Science:

  • Statistical physics
  • Condensed matter theory
  • Non-equilibrium systems

Background:

  • Universal scaling describes how system properties change with scale in physical systems.
  • Driven systems with quenched disorder present complex behaviors not fully understood.
  • The Kardar-Parisi-Zhang (KPZ) equation is a fundamental model for surface growth and driven systems.

Purpose of the Study:

  • To investigate if quenched disorder can induce continuously varying universality classes in driven systems.
  • To explore the role of disorder distribution structure in determining scaling behavior.
  • To analyze the relevance of disorder as a perturbation in the renormalization group sense.

Main Methods:

  • Analysis of the Kardar-Parisi-Zhang (KPZ) equation with quenched disorder.
  • Renormalization group (RG) techniques to assess disorder relevance.
  • Examination of disorder distributions with specific structural properties.

Main Results:

  • Scaling exponents can depend continuously on a dimensionless parameter in the disorder distribution.
  • This continuous variation occurs when the disorder is a relevant perturbation in the RG sense.
  • The findings are generic, applying to disorders with or without long-range correlations.

Conclusions:

  • Quenched disorder can lead to a continuous spectrum of universality classes in driven systems.
  • The nature of the disorder distribution is crucial for determining scaling behavior.
  • Results have implications for understanding generic driven systems with quenched disorder.
