Hamiltonian: meaning, definitions and examples
⚛️
Hamiltonian
[ ˌhæmɪlˈtoʊniən ]
physics
A Hamiltonian is a mathematical operator corresponding to the total energy of a system in quantum mechanics. It is used to describe the dynamics of the system and is an essential concept in theoretical physics.
Synonyms
energy operator, total energy operator.

Word | Description / Examples |
---|---|
Hamiltonian |
This term is commonly used in physics, particularly in quantum mechanics, to describe the total energy operator of a system. It encompasses both the kinetic and potential energy of a system and is essential for formulating the Schrödinger equation.
|
energy operator |
Used in the context of quantum mechanics and field theory, this general term refers to any operator that is associated with the energy of a system. Unlike 'Hamiltonian,' it doesn't necessarily imply the inclusion of both kinetic and potential energy.
|
total energy operator |
This term specifically refers to an operator that accounts for all forms of energy within a system and is synonymous with 'Hamiltonian' in many contexts. It is less frequently used but emphasizes the inclusion of all energy components.
|
Examples of usage
- The Hamiltonian operator plays a crucial role in determining the behavior of quantum systems.
- In quantum mechanics, the time evolution of a system is governed by the Hamiltonian.
mathematics
In mathematics, a Hamiltonian is a function used to describe the state of a dynamic system in terms of position and momentum variables. It is often used in classical mechanics and differential equations.
Synonyms
Hamilton function, Hamiltonian function.

Examples of usage
- The Hamiltonian function can be used to derive the equations of motion for a physical system.
- Hamiltonian mechanics provides a powerful framework for understanding the behavior of dynamical systems.

Etymology
The term 'Hamiltonian' is named after Sir William Rowan Hamilton, an Irish mathematician, and physicist who introduced the concept in the 19th century. Hamilton's work on mechanics and optics laid the foundation for the development of the Hamiltonian formalism in physics and mathematics.
