Schwarzschild Radius and Event Horizon01:21

Schwarzschild Radius and Event Horizon

2.2K
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

Magnetostatic Boundary Conditions

1.9K
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Atomic Nuclei: Larmor Precession Frequency

3.5K
The earth's gravitational field produces a 'twisting force' perpendicular to the angular momentum of a spinning mass (such as a spinning top) that causes the mass to 'wobble' around the gravitational field axis in a phenomenon called precession. Similarly, the magnetic moment (μ) of a spinning nucleus precesses due to an external magnetic field directed along the z-axis. The precession of the magnetic moment vector about the magnetic field is called Larmor precession,...

Kepler's First Law of Planetary Motion

4.9K
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.
On the other hand,...

Coriolis Force01:23

Coriolis Force

7.7K
An accelerating particle experiences a force equal to the mass multiplied by the acceleration in an inertial frame of reference. Consider a particle in a non-inertial frame of reference, such as a sliding ball on a rotating table. The acceleration of the ball in this rotating reference frame is different than in the intertial frame, which modifies its equation of motion. The fictitious forces acting additionally on a rotating frame of reference alter Newton's Second Law expression.

Gravity between Spherical Bodies01:27

Gravity between Spherical Bodies

7.2K
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...

This summary is machine-generated.

Researchers found stable vortons, which are spinning flux loops, in a gauged U(1)×U(1) model. These stable vortons could have implications for dark matter, quantum chromodynamics, and condensed matter physics.

Area of Science:

  • Theoretical Physics
  • High Energy Physics
  • Cosmology

Background:

  • Vortons, spinning flux loops, were previously hypothesized but lacked concrete field theory solutions.
  • The stability of vortons remained an open question due to the absence of explicit solutions.

Purpose of the Study:

  • To construct explicit, stationary solutions for vortons within the gauged U(1)×U(1) model.
  • To investigate the stability of these vorton solutions under dynamical evolution.

Main Methods:

  • Construction of a family of stationary vorton solutions characterized by charge and angular momentum.
  • Analysis of the stability of these solutions through 3+1 nonlinear dynamical evolution.

Main Results:

  • Explicit stationary vorton solutions were successfully constructed.
  • Most vorton solutions were found to be unstable upon perturbation.
  • Thick vortons with small radii demonstrated stability during nonlinear dynamical evolution, providing the first evidence of stable vortons.

Conclusions:

  • The study provides the first concrete evidence for the existence of stable vortons.
  • Stable vortons have potential implications across various physics domains, including dark matter in cosmology, quantum chromodynamics (QCD), and condensed matter physics.
