Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
