Summary
We investigated the structure of a vortex in low-density superfluid neutron matter. Our findings reveal a depleted core density, a novel characteristic for vortex states in Fermi superfluids.
Area of Science:
- Nuclear Physics
- Condensed Matter Physics
- Astrophysical Matter
Background:
- Superfluid neutron matter is a key component in understanding neutron stars.
- Vortices are fundamental excitations in superfluids, influencing their dynamics.
- Previous studies have not fully characterized vortex structures in low-density neutron matter.
Purpose of the Study:
- To investigate the structure of a vortex in low-density superfluid neutron matter.
- To determine the matter density profile of such a vortex.
- To identify novel features of vortex states in Fermi superfluids.
Main Methods:
- Employed a fully self-consistent theoretical approach.
- Analyzed the spatial distribution of matter within the vortex core.
- Utilized theoretical models applicable to Fermi superfluids.
Main Results:
- The matter density profile of a vortex exhibits significant depletion in the core region.
- This depletion is a newly observed feature for vortex states in Fermi superfluids.
- The self-consistent approach provided detailed insights into the vortex structure.
Conclusions:
- The study reveals a unique density depletion in the core of vortices in low-density superfluid neutron matter.
- This finding offers new perspectives on the behavior of matter under extreme conditions.
- Further research is needed to explore the implications of this feature in astrophysical contexts.

02:22Structures of Solids
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...
00:59Atomic Nuclei: Nuclear Magnetic Moment
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...
01:03Atomic Nuclei: Nuclear Spin State Overview
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...
01:14Atomic Nuclei: Nuclear Spin State Population Distribution
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.
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...
01:23Magnetic Field due to Moving Charges
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
