1704Norris Ideal World ii. ii. 60 They are also so self-consistent as in consequence of their common principle to hold that they do not think. 1817Coleridge Statesm. Man. 5 Imposture, organized into a comprehensive and self-consistent whole. 1843Penny Cycl. XXVII. 199/2 An accurate and self-consistent system of weights and measures.
b. Physics. Of a trial solution of Schrödinger's equation for a nucleus with more than one electron: consistent with its own postulates (see quots.).
1928D. R. Hartree in Proc. Cambr. Philos. Soc. XXIV. 113 If the final field is the same as the initial field, the field will be called ‘self-consistent’. 1958Sykes & Bell tr. Landau & Lifshitz' Quantum Mechanics x. 232 Schrödinger's equation for atoms containing more than one electron cannot be directly solved in practice, even by numerical methods. Approximate methods of calculating the energies and wave functions of the stationary states of the atoms are therefore important. The most important of these methods is what is called the self-consistent field method. The idea of this method consists in regarding each electron in the atom as being in motion in the ‘self-consistent field’ due to the nucleus together with all the other electrons. 1974Eisberg & Resnick Quantum Physics ix. 347 It might seem that there is no way to find the net potential of an atom at intermediate distances from its center... But it can be taken care of by demanding that the net potential be self-consistent.
Hence self-conˈsistently adv.

Hjelmslev's Prolegomena to Theory of Lang. 9 We require of linguistic theory that it enable us to describe self-consistently and exhaustively all conceivable or possible Danish texts. 1973Physical Rev. B. VII. 674 Energy bands, Fermi surfaces, and densities of states of calcium as a function of lattice constant have been calculated self-consistently by the augmented-plane-wave method. |
