Proceedings. Mathematical, Physical, and Engineering Sciences
|March 22, 2016
Summary
We demonstrate bright soliton generation in non-equilibrium Bose-Einstein condensates. Analytical and numerical methods reveal unique inter- and intra-species competition dynamics.
Area of Science:
- Quantum physics
- Non-equilibrium statistical mechanics
Background:
- Bose-Einstein condensates (BECs) are quantum states of matter.
- Non-equilibrium systems exhibit complex dynamics not found in equilibrium.
Purpose of the Study:
- To theoretically demonstrate bright soliton generation in spinor non-equilibrium BECs.
- To elucidate the unique features of inter- and intra-species competition in these systems.
Main Methods:
- Theoretical demonstration using a generalized non-conservative Lagrangian.
- Derivation of analytical expressions for bright solitons.
- Detailed numerical analysis to support theoretical findings.
Main Results:
- Analytical expressions for bright (half) solitons were derived.
- Unique features of inter- and intra-species competition were elucidated.
- Numerical analysis confirmed rich soliton dynamics, including instability and cross-interactions.
Conclusions:
- A mechanism for bright soliton generation in spinor non-equilibrium BECs is theoretically demonstrated.
- The study highlights the complex dynamics arising from competition in non-equilibrium systems.
- Analytical and numerical approaches provide a comprehensive understanding of soliton behavior.

8.4K
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...

Electromagnetic waves can travel in the vacuum as well as in matter. For example light, which is an electromagnetic wave, can travel through air, water, or glass.
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.

16.9K
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.

01:01Energy Bands in Solids
2.3K
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

01:23Atomic Nuclei: Nuclear Relaxation Processes
1.4K
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.
