    • n Harmonium här*mō"nĭ*ŭm A musical instrument, resembling a small organ and especially designed for church music, in which the tones are produced by forcing air by means of a bellows so as to cause the vibration of free metallic reeds. It is now made with one or two keyboards, and has pedals and stops.

    • n harmonium One of the forms of the reed-organ (which see). The essential difference between the harmonium and the so called American organ lies in the fact that in the former the air is compressed by the bellows and thence driven out through the reeds, while in the latter the bellows produce a vacuum into which the outside air is drawn through the reeds. Harmonium is the usual term in England and France for all reed-organs.

In science:

In the early years of the theory, Heisenberg invented an exactly solvable model, here called harmonium, as a proxy for the spectral problem of two-electron atoms .
Testing one-body density functionals on a solvable model
The integrability and solvability of harmonium enables one to test accurately how proposed density matrix functionals behave for this particular system .
Testing one-body density functionals on a solvable model
There is another particularity of harmonium: for its ground state, the M¨uller functional, evaluated on the exact one-body reduced density matrix, yields the correct value of the energy .
Testing one-body density functionals on a solvable model
Here we confirm by a different method this surprising coincidence, and we catalogue the predictions for harmonium by several proposed two-body functionals, measured against the exact model.
Testing one-body density functionals on a solvable model
In section 2 we briefly recall the analytical phase-space treatment for the harmonium ground state; this also helps to introduce the notation.
