ˈpseudopotential Physics.
[f. pseudo- + potential a. and n.]
A potential distribution assumed for the purposes of calculation as an approximation to the actual potential.
1956C. Herring in R. Breckenridge et al. Proc. Conf. Photoconductivity, Atlantic City, 1954 86 The idea of using such a repulsive pseudopotential is due to Hellman..and has been applied with some success to molecules..and metals. 1965Rev. Mod. Physics XXXVII. 388/2 Since we are making the Born approximation, the best choice for v(r) is a pseudopotential that fits free (p, p) scattering. 1968Times 2 Dec. 17/1 The theory, known as the ‘pseudopotential method’, does not allow the properties of the metal to be calculated without guessing either the shape of the wave or the force exerted by the atoms on the electrons. 1976Coles & Caplin Electronic Struct. Solids iv. 93 Pseudopotential methods are now sufficiently finely developed that not only can accurate band structures be calculated for metals (and alloys) but also meaningful estimates can be made of the difference in energy of different crystallographic structures for an element. |
