Notes Charged oscillator in an electric field In quantum mechanics, the behaviour of a charged oscillator in an electric field can be described using the Schrödinger equationF = qeF = - dV/ dXdv = ...
Notes Stationary Perturbation theory Stationary perturbation theory is a mathematical method used in quantum mechanics to approximate the behaviour of a quantum system when subjected to a small external perturbation. The term …
Notes Normal helium atom A normal helium atom, also known as helium-4, is the most common and stable isotope of helium. In quantum mechanics, the description of a helium atom involves the application of ...
Notes Solution of radiative transfer equation for plane parallel atmosphere The radiative transfer equation describes how electromagnetic radiation (such as light) propagates through a medium. In the case of a plane-parallel atmosphere, the radiative transfer equation can be …
Notes Various stages of star formation Star formation is a complex process that involves the gravitational collapse of a region within a large molecular cloud, leading to the formation of a protostar and, eventually, a main-sequence ...
Notes Wave function The wave equation is a partial differential equation that describes how waves propagate over time and space. It is a fundamental equation in physics and is used to model a ...
Notes Scattering of electromagnetic radiation The scattering of electromagnetic radiation refers to the process by which electromagnetic waves deviate from their original path due to interactions with particles or obstacles in their path. This …
Notes Hamiltonian Formulation The Hamiltonian formulation is a mathematical approach in classical mechanics and quantum mechanics that provides an alternative description of the dynamics of a physical system. It is named after …
