Reduced Density Matrices: Coulson’s Challenge: Lecture Notes in Chemistry, cartea 72

Autor A.J. Coleman, V. I. Yukalov
en Limba Engleză Paperback – 14 apr 2000
The authors demonstrate that the essential information about order in, and energy levels of physical systems is encapsulated in the second order reduced density matrix. They have discovered an algorithm to obtain a reasonable accurate expression for the 2-matrix of an N-particle state to make nearly all properties of matter which are of interest to chemists and physicists accessible.
