Differential Form of Maxwell's Equations01:17

Differential Form of Maxwell's Equations

James Clerk Maxwell (1831–1879) was one of the significant contributors to physics in the nineteenth century. He is probably best known for having combined existing knowledge of the laws of electricity and the laws of magnetism with his insights to form a complete overarching electromagnetic theory, represented by Maxwell's equations. The four basic laws of electricity and magnetism were discovered experimentally through the work of physicists such as Oersted, Coulomb, Gauss, and Faraday.
Coulomb's Law and The Principle of Superposition01:15

Coulomb's Law and The Principle of Superposition

Coulomb's Law describes the force experienced by two point charges under each other's presence. But what if there are more than two charges? For example, if there is a third charge, does it experience a force that is a simple combination of the individual forces due to the first two charges? Can it be described mathematically?
The Principle of Superposition answers the question. Yes, Coulomb's Law applies to each pair of charges, and the net force on each charge is the vector sum of the...
Cartesian Form for Vector Formulation01:26

Cartesian Form for Vector Formulation

The Cartesian form for vector formulation is a process to calculate  the moment of force using the position and force vectors. The moment of force is defined as the cross-product of these vectors, making it a vector quantity. The Cartesian form of the position and force vectors involves unit vectors, which can be used to express the cross-product in determinant form.
Gauss's Law in Dielectrics01:17

Gauss's Law in Dielectrics

Consider a polar dielectric placed in an external field. In such a dielectric, opposite charges on adjacent dipoles neutralize each other, such that the net charge within the dielectric is zero. When a polar dielectric is inserted in between the capacitor plates, an electric field is generated due to the presence of net charges near the edge of the dielectric and the metal plates interface. Since the external electrical field merely aligns the dipoles, the dielectric as a whole is neutral. An...
Couples: Scalar and Vector Formulation01:21

Couples: Scalar and Vector Formulation

One might wonder how the captain of a large ship can navigate through the ocean with just a turn of the steering wheel. The answer lies in the concept of two parallel forces that are equal in magnitude and opposite sense, creating a couple moment.
A couple moment is a rotational force that tends to rotate the steering wheel. The wheel's rotation can either be in a clockwise or anticlockwise direction. The right-hand rule is a helpful method for determining the direction of a couple moment. To...
Symmetry in Maxwell's Equations01:28

Symmetry in Maxwell's Equations

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

Area of Science:

  • Theoretical physics
  • High-energy physics
  • Quantum field theory

Background:

  • A recent duality between color and kinematics has been proposed for scattering amplitudes.
  • This duality suggests a new, unexpected structure within gauge theory and gravity.

Purpose of the Study:

  • To explore a deeper connection between color and kinematics in scattering amplitudes.
  • To reorganize amplitudes by swapping the roles of color and kinematics, analogous to standard color decomposition.

Main Methods:

  • Reorganizing scattering amplitudes into a form resembling standard color decomposition.
  • Swapping the roles of color and kinematics within this new organization.
  • Imposing conditions similar to Kleiss-Kuijf relations to establish invertibility.

Main Results:

  • Demonstrated a deeper relationship between color and kinematics beyond the initial duality.
  • Developed an invertible method to reorganize amplitudes by swapping color and kinematic roles.
  • Showcased a structure reminiscent of standard color decomposition but with roles interchanged.

Conclusions:

  • The proposed reorganization offers a new perspective on scattering amplitudes.
  • The invertibility of the transformation is established through Kleiss-Kuijf-like conditions.
  • The findings open avenues for extensions to loop-level calculations in quantum field theory.
