Magnetic Field of a Solenoid01:18

Magnetic Field of a Solenoid

6.1K
A solenoid is a conducting wire coated with an insulating material, wound tightly in the form of a helical coil. The magnetic field due to a solenoid is the vector sum of the magnetic fields due to its individual turns. Therefore, for an ideal solenoid, the magnetic field within the solenoid is directly proportional to the number of turns per unit length and the current. Conversely, the magnetic field outside the solenoid is zero.
Consider a solenoid with 100 turns wrapped around a cylinder of...

Solenoids

3.4K
A solenoid is a conducting wire coated with an insulating material, wound tightly in the form of a helical coil. The magnetic field for a solenoid is the vector sum of the magnetic field due to its individual turns. For an ideal solenoid, the magnetic field inside is almost uniform and parallel to the solenoid axis, while the magnetic field outside the solenoid is nearly zero.
Each turn in a solenoid can be approximated as a circular current carrying coil that generates a dipole moment. The...

Molecular and Ionic Solids

20.4K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Oscillations In An LC Circuit01:30

Oscillations In An LC Circuit

3.2K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Solvating Effects02:12

Solvating Effects

9.0K
An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the relative stability of conjugate bases for compounds with different pKa values. This lesson details, in-depth, the principle of solvating effects. The strength of an acid and the stability of its corresponding conjugate base are determined using pKa values. This observed relationship is a consequence of solvation, which is the interaction...

Speed of Sound in Solids and Liquids00:51

Speed of Sound in Solids and Liquids

4.0K
Most solids and liquids are incompressible—their densities remain constant throughout. In the presence of an external force, the molecules tend to restore to their original positions, which is only possible because the constituents interact. The interactions help the constituents pass on information about external disturbances, like sound waves. Therefore, sound waves travel faster through these media. Compared to solids, the constituents in a liquid are less tightly bound. Thus, sound...

Area of Science:

  • Nonlinear physics
  • Wave phenomena
  • Optics

Background:

  • Solitons are fundamental in nonlinear physics, arising from integrable nonlinear equations.
  • Most multidimensional systems lack integrability, hindering soliton existence in higher dimensions.
  • Lump solitons, solutions to the Kadomtsev-Petviashvili (KP) equation, propagate unperturbed but have never been experimentally observed.

Purpose of the Study:

  • To achieve the first experimental observation of a lump soliton.
  • To demonstrate the existence and properties of lump solitons in a physical system.
  • To confirm the integrable nature of observed lump solitons through their interactions.

Main Methods:

  • Realized lump solitons in nonlinear optics using a photorefractive crystal.
  • Employed paraxial diffraction and defocusing nonlinearity governed by the (2+1)D nonlinear Schrödinger (NLS) equation.
  • Tailored input field and nonlinearity to match the hydrodynamic KP integrable regime.

Main Results:

  • Successfully observed self-localized lump solitons propagating unaltered with transverse velocity.
  • Confirmed the integrable nature of the lump soliton through experimental observation.
  • Reported the first instance of elastic collisions between lump solitons in two dimensions.

Conclusions:

  • This study provides the first experimental evidence of lump solitons.
  • The observation validates theoretical predictions of integrable solitons in high dimensions.
  • This work initiates a new era for research into nonlinear systems and wave dynamics.
