Holes in Quantum Chemistry
An alternate meaning for the term electron hole is used in computational chemistry. In coupled cluster methods, the ground (or lowest energy) state of a molecule is interpreted as the "vacuum state"—conceptually, in this state there are no electrons. In this scheme, the absence of an electron from a normally-filled state is called a "hole" and is treated as a particle, and the presence of an electron in a normally-empty state is simply called an "electron". This terminology is almost identical to that used in solid-state physics.

Famous quotes containing the words holes in, holes, quantum and/or chemistry:
“But Father John went up,
And Father John went down;
And he wore small holes in his shoes,
And he wore large holes in his gown.”
—William Butler Yeats (1865–1939)
“Keyholes are the occasions of more sin and wickedness, than all other holes in this world put together.”
—Laurence Sterne (1713–1768)
“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (1896–1948)
“The chemistry of dissatisfaction is as the chemistry of some marvelously potent tar. In it are the building stones of explosives, stimulants, poisons, opiates, perfumes and stenches.”
