In quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero.
In quantum field theory, the Casimir effect and the Casimir–Polder force are physical forces arising from a quantized field.
The Compton wavelength is a quantum mechanical property of a particle.
In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928.
A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy.
Erwin Rudolf Josef Alexander Schrödinger (12 August 1887 – 4 January 1961), sometimes written as or, was a Nobel Prize-winning Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation (stationary and time-dependent Schrödinger equation) and revealed the identity of his development of the formalism and matrix mechanics.
In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation.
The Foldy–Wouthuysen transform is widely used in high energy physics.
German (Deutsch) is a West Germanic language that is mainly spoken in Central Europe.
In quantum mechanics, a Hamiltonian is an operator corresponding to the total energy of the system in most of the cases.
In physics, the Heisenberg picture (also called the Heisenberg representation) is a formulation (largely due to Werner Heisenberg in 1925) of quantum mechanics in which the operators (observables and others) incorporate a dependency on time, but the state vectors are time-independent, an arbitrary fixed basis rigidly underlying the theory.
A hydrogen-like ion is any atomic nucleus which has one electron and thus is isoelectronic with hydrogen.
In physics, the Lamb shift, named after Willis Lamb, is a difference in energy between two energy levels 2S1/2 and 2P1/2 (in term symbol notation) of the hydrogen atom which was not predicted by the Dirac equation, according to which these states should have the same energy.
In quantum mechanics, the position operator is the operator that corresponds to the position observable of a particle.
Stochastic electrodynamics (SED) is an extension of the de Broglie–Bohm interpretation of quantum mechanics, with the electromagnetic zero-point field (ZPF) playing a central role as the guiding pilot-wave.
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity.
In quantum field theory, the quantum vacuum state (also called the quantum vacuum or vacuum state) is the quantum state with the lowest possible energy.
In physics, a wave packet (or wave train) is a short "burst" or "envelope" of localized wave action that travels as a unit.
