Summary
This study explores stable two-dimensional quantum droplets in Bessel lattices. Vorticity affects droplet stability limits, and nested droplets with varying vorticities show enhanced stability.
Area of Science:
- Quantum physics
- Nonlinear optics
- Condensed matter theory
Background:
- Zeroth-order Bessel lattices support unique quantum droplet configurations.
- The Gross-Pitaevskii equations with Lee-Huang-Yang corrections model quantum droplet dynamics.
Purpose of the Study:
- Investigate the stability of two-dimensional quantum droplets in Bessel lattices.
- Analyze the impact of vorticity on droplet stability regions.
- Explore the formation and stability of nested composite quantum droplet structures.
Main Methods:
- Theoretical framework development.
- Direct numerical simulations of quantum droplet evolution.
- Analysis of stability criteria based on Gross-Pitaevskii equations with Lee-Huang-Yang corrections.
Main Results:
- Stable zero-vorticity and vortical annular quantum droplets are formed.
- Vorticity influences the upper stability limit of quantum droplets, not the lower limit.
- Stable nested concentric multiring structures of quantum droplets are constructed.
- Nested vortical droplets exhibit enhanced stability, especially with varying vorticities.
Conclusions:
- Zeroth-order Bessel lattices provide a platform for stable quantum droplet configurations.
- Vorticity is a key parameter in controlling quantum droplet stability.
- Nested quantum droplet structures offer superior stability compared to homogeneous vorticity configurations.

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.

01:10First Law: Particles in One-dimensional Equilibrium
6.8K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

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...

01:23Equilibrium Conditions for a Particle
1.0K
When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...

02:39Phase Transitions: Vaporization and Condensation
17.1K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase...

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.
