Summary
Rotation significantly alters quantum turbulence dynamics, creating new regimes unlike classical turbulence. Understanding these distinct states is crucial for quantum fluids and condensed matter physics.
Area of Science:
- Fluid Dynamics
- Quantum Mechanics
- Condensed Matter Physics
Background:
- Quantum turbulence exhibits similarities to classical turbulence in homogeneous, isotropic conditions.
- Rotation introduces significant deviations in quantum fluid dynamics compared to classical expectations.
Purpose of the Study:
- To explore the phenomenology of rotating quantum turbulence.
- To identify and characterize new dynamical regimes absent in classical analogues.
- To investigate the interplay of rotation, quantization, and nonlinearities in quantum fluids.
Main Methods:
- Review of theoretical, experimental, and numerical developments in rotating quantum turbulence.
- Presentation of new numerical simulations to map dynamical regimes.
- Analysis of quantum fluid dynamics across different rotation rates (slow, rapid) and quantum regimes (low Landau level).
Main Results:
- Rotation introduces novel regimes in quantum turbulence with no classical counterparts.
- Distinct dynamical behaviors are observed in slowly rotating, rapidly rotating, and low Landau level regimes.
- The interplay of rotation, quantization, and condensed matter physics dictates the observed dynamics.
Conclusions:

01:08Equation of Rotational Dynamics
Angular variables are introduced in rotational dynamics. Comparing the definitions of angular variables with the definitions of linear kinematic variables, it is seen that there is a mapping of the linear variables to the rotational ones. Linear displacement, velocity, and acceleration have their equivalents in rotational motion, which are angular displacement, angular velocity, and angular acceleration. Similar to the rotational variables, a mapping exists from Newton's second law of motion...
01:09Conservation of Angular Momentum
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Considering a system that consists of n tiny particles, the angular momentum of any tiny particle may change, but the system's total angular momentum would remain constant. The principle of conservation of angular momentum only considers the net external torque acting on the system. While there are internal forces exerted by different particles within the system that also produce internal...
02:45The Quantum-Mechanical Model of an Atom
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra. Schrödinger...
01:18Conservation of Angular Momentum: Application
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Examples of such systems include a freely spinning bicycle tire that slows over time due to torque arising from friction, or the slowing of Earth's rotation over millions of years due to frictional forces exerted on tidal deformations. However in the absence of a net external torque, the angular momentum remains conserved. The conservation of angular momentum principle requires a change...
01:23Atomic Nuclei: Nuclear Relaxation Processes
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. This...
01:26Rotational Motion about a Fixed Axis
A rigid body's rotation around a fixed axis makes every point within it trace a circular path around a specific line or point. The term given to this type of spinning is defined by the angular position, symbolized by the angle θ. This angle is gauged from a static reference line to the revolving object. From this angular position, any variation is referred to as angular displacement, denoted by dθ. The extent of this displacement can be calculated in degrees, radians, or revolutions, where one...
