Summary
Quantum turbulence shows Kolmogorov turbulence from vortex orientation correlations. Intermittency arises from spatial arrangements, linking quantum and classical flow models for better understanding.
Area of Science:
- Physics
- Fluid Dynamics
- Quantum Mechanics
Background:
- Understanding turbulent flows and their intermittency remains a significant challenge in physics.
- Turbulent flows can be conceptualized as interacting vortices, a model that holds true for quantum turbulence composed of discrete vortex filaments.
Purpose of the Study:
- To investigate the statistics of velocity circulation in both quantum and classical turbulence.
- To establish a connection between the intermittency observed in quantum and classical turbulence.
Main Methods:
- Statistical analysis of velocity circulation in quantum and classical turbulent flows.
- Correlation analysis of vortex orientations in quantum turbulence.
- Linking the spatial distribution of vortices in quantum turbulence to energy dissipation in classical turbulence.
Main Results:
- Kolmogorov turbulence emerges in quantum flows due to the correlation of vortex orientations.
- Intermittency in quantum turbulence originates from the non-trivial spatial arrangement of vortices.
- A link is established between the spatial distribution of vortices in quantum turbulence and coarse-grained energy dissipation in classical turbulence.
Conclusions:
- The study reveals that vortex orientation correlations drive Kolmogorov turbulence in quantum flows.
- The spatial arrangement of vortices is identified as the source of intermittency in quantum turbulence.
- This research enables the application of classical turbulence intermittency models to quantum turbulence, advancing the understanding of both.

Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent...

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Irrotational flow is characterized by fluid motion where particles do not rotate around their axes, resulting in zero vorticity. For a flow to be irrotational, the curl of the velocity field must be zero. This imposes specific conditions on velocity gradients. For instance, to maintain zero rotation about the z-axis, the gradient condition:

The divergence of a vector field at a point is the net outward flow of the flux out of a small volume through a closed surface enclosing the volume, as the volume tends to zero. More practically, divergence measures how much a vector field spreads out or diverges from a given point. For an outgoing flux, conventionally, the divergence is positive. The diverging point is often called the "source" of the field. Meanwhile, the negative divergence of a vector field at a point means that the...

01:18First Law: Particles in Two-dimensional Equilibrium
6.6K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
