A new constructive approach for deriving a quantum field chemistry (wc) is proposed. As a matter of fact, the approach is a direct application of the concept of spontaneously broken symmetry of a free-electron-field vacuum to the exact definition of a condensed-state chemical microstructure. The main idea is to identify the properly modified ground states of the vacuum with ground states of some compact quasi-molecular systems condensed in a set of "kinY- Such clusters may be used to simulate some active centers that bear the responsibility for strong effects of nonlinearity and dissipation in condensed states. Some results of AwF-calculation of small active Rh-clusters (n = 2,3,4) are taken under consideration to illustrate that such clusters resemble neither fragments of bulk solids nor molecules in a gas.

A quantum field mechanics of an electron subsystem in 3D physical space as the topology of compact atomic clusters with spontaneously broken local canonical symmetry is used for investigation of different types of microdefects in the condensed state of transition metals. The theory is illustrated with results of calculation of small compact Fen clusters (n = 2,6,14).
