摘要
En 中文
On the sole basis of the knowledge of the expectation values of several physical observables, an inferred density matrix for spherical alkali-metal clusters is obtained. No explicit knowledge of any Hamiltonian model is assumed. A combination of information theory with the pseudoinverse variational formalism is employed, and densities for spherical Na clusters are obtained. [S0163-1829(99)09127-4].
