Oscillations about an Equilibrium Position01:04

Oscillations about an Equilibrium Position

6.5K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Oscillations In An LC Circuit

2.9K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Damped Oscillations

6.6K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

The de Broglie Wavelength

32.5K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Stability of Equilibrium Configuration01:23

Stability of Equilibrium Configuration

697
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

Forced Oscillations01:06

Forced Oscillations

7.4K
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.

Summary

We investigated entanglement dynamics in the Ising spin chain. Bound states cause oscillations and suppress linear growth, while linear growth is confirmed for transverse field quenches.

Area of Science:

  • Quantum physics
  • Condensed matter theory
  • Statistical mechanics

Background:

  • The Ising spin chain is a fundamental model in condensed matter physics.
  • Understanding entanglement dynamics is crucial for quantum information science.

Purpose of the Study:

  • To analyze entanglement dynamics in the Ising spin chain under longitudinal and transverse fields.
  • To extend analytical techniques beyond standard lattice integrability.

Main Methods:

  • Analytical calculations for field quenches in the scaling limit.
  • Numerical simulations of the lattice model for validation.
  • Investigation of bound states' impact on entanglement entropy.

Main Results:

  • Analytical results for longitudinal field quenches agree with numerical simulations.
  • Bound states induce oscillations and suppress linear entanglement growth.
  • Linear entanglement growth is proven for transverse field quenches at zero longitudinal field.

Conclusions:

  • Oscillations and linear growth in entanglement entropy are not solely due to integrability or its breaking.
  • The study provides new insights into quantum entanglement in critical systems.
