Notes Degenerate perturbation theory Degenerate perturbation theory is a method used in quantum mechanics to analyze systems where the non-perturbed Hamiltonian operator has degenerate energy levels. In quantum mechanics, a degenerate …
Notes Vander Wall's Interaction Van der Waals interactions, often referred to as van der Waals forces, are a type of weak, non-covalent interaction that occurs between atoms and molecules. These forces play a crucial ...
Notes Angular distribution of Power The angular distribution of power, often referred to as the radiation pattern or angular response, is a concept commonly used in the fields of physics, engineering, and electronics. It describes ...
Notes Distribution in frequency and angle of energy radiated by an accelerated charge The distribution in frequency and angle of energy radiated by an accelerated charge is a topic within classical electrodynamics. When a charged particle undergoes acceleration, it emits …
Notes Covariant form of equation of motion of a charged particle moving under a influence of electromagnetic field The covariant form of the equation of motion for a charged particle moving under the influence of an electromagnetic field is described by the Lorentz force equation. This equation accounts ...
Notes Relativistic Hamiltonian for charged particle in external electromagnetic field The relativistic Hamiltonian for a charged particle moving in an external electromagnetic field is derived from the Dirac equation, which is the relativistic quantum mechanical equation describing …
Notes Two dimensional Harmonic Oscillator A two-dimensional harmonic oscillator is a physical system in which a particle is subject to forces that can be described by two independent harmonic potentials in two perpendicular directions. This …
Notes Harmonically bound charge A "harmonically bound charge" typically refers to a charged particle that is subjected to a restoring force that follows a harmonic or sinusoidal pattern when it is displaced from its ...
