Extrapolating the correlation energy

We present a general scheme for calculating the correlation energy in molecular systems by extrapolation of an energy Ž . expression, E t , obtained from a modified Hamiltonian whose range is reduced to induce localization of the physical Ž . interactions. The variable t is introduced such that one recovers the physical system for ts0 and E t s0 for tTM`. We show that very accurate correlation ...

Conventional Quantum Chemical Correlation Energy versus Density - Functional Correlation Energy

We analyze the difference between the correlation energy as defined within the conventional quantum chemistry framework and its namesake in density-functional theory. Both quantities are rigorously defined concepts; one finds that E QC c ≥ E DF T c. We give numerical and analytical arguments suggesting that the numerical difference between the two rigorous quantities is small. Finally, approxim...

Long-range correlation energy calculated from coupled atomic response functions.

An accurate determination of the electron correlation energy is an essential prerequisite for describing the structure, stability, and function in a wide variety of systems. Therefore, the development of efficient approaches for the calculation of the correlation energy (and hence the dispersion energy as well) is essential and such methods can be coupled with many density-functional approximat...

On the Correlation between Energy and Pit

In this paper, we describe a set of experiments that examine the correlation between energy and pitch accent. We tested the discriminative power of the energy component of frequency subbands with a variety of frequencies and bandwidths on read speech spoken by four native speakers of Standard American English, using an analysis by classification approach. We found that the frequency region most...
