Oscillations about an Equilibrium Position01:04

Oscillations about an Equilibrium Position

7.1K
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...

Atomic Nuclei: Nuclear Relaxation Processes

1.3K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.

Interference and Diffraction

53.0K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Oscillations In An LC Circuit

3.3K
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

Atomic Nuclei: Types of Nuclear Relaxation

1.1K
Nuclear relaxation restores the equilibrium population imbalance and can occur via spin–lattice or spin–spin mechanisms, which are first-order exponential decay processes.
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers...

Interference and Superposition of Waves

7.2K
When two waves of the same nature occur in the same region simultaneously, they result in interference. Interference of waves implies that the net effect of the waves is the sum of the individual waves' effects. However, it does not imply that the individual waves affect the propagation of other waves.
Interference occurs in mechanical waves, such as sound waves, waves on a string, and surface water waves. Mechanical waves correspond to the physical displacement of particles. Hence,...

Summary

Entanglement prethermalization (EP) is a state where subsystems appear thermal but the whole system remains nonthermal due to quantum entanglement. This study shows a simple model captures EP essentials, with perturbation affecting its lifetime.

Area of Science:

  • Quantum physics
  • Statistical mechanics
  • Condensed matter theory

Background:

  • Entanglement prethermalization (EP) describes a unique non-equilibrium state where subsystems thermalize individually while the whole system remains nonthermal due to entanglement.
  • Understanding EP is crucial for comprehending complex quantum systems dynamics.

Purpose of the Study:

  • To theoretically investigate the dynamics of entanglement prethermalization (EP) in a simplified quantum system.
  • To analyze how a composite system evolves after a sudden change, specifically a coherent split of a harmonic potential.

Main Methods:

  • The study employs theoretical analysis of a one-dimensional system with two interacting bosons confined in a harmonic potential.
  • The model simulates an interaction quench between two harmonic oscillators to study EP dynamics.
  • Generalized Gibbs ensemble is used to describe the total system, incorporating nonlocal conserved quantities.

Main Results:

  • The model successfully demonstrates EP, with individual subsystems reaching approximate thermal equilibrium while the total system remains entangled.
  • A generalized Gibbs ensemble precisely describes the total system when nonlocal conserved quantities are considered.
  • The presence of a symmetry-breaking perturbation leads to a quasi-stationary EP plateau before eventual thermalization.

Conclusions:

  • A simple model of split harmonic oscillators effectively captures the core features of entanglement prethermalization.
  • The lifetime of the EP state is analytically shown to be inversely proportional to the magnitude of symmetry-breaking perturbations.
  • This research provides insights into the stability and dynamics of non-equilibrium quantum states.
