General physics

isobaric process

Physics; General physics

In which pressure remains constant.

Perturbation theory

Physics; General physics

In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one.

Stark effect

Physics; General physics

The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to presence of an external static electric field.

Many-body theory

Physics; General physics

The many-body theory (or many-body physics) is an area of physics which provides the framework for understanding the collective behaviour of vast assemblies of interacting particles.

Trajectory

Physics; General physics

In fluid mechanics, meteorology, and oceanography, a trajectory traces the motion of a single point, often called a parcel, in the flow.

Particle in a ring

Physics; General physics

In quantum mechanics, the case of a particle in a one-dimensional ring is similar to the particle in a box.

Kondo effect

Physics; General physics

In physics, the Kondo effect describes the scattering of conduction electrons in a metal due to magnetic impurities. It is a measure of how electrical resistivity changes with temperature.
