  Applications of Pade approximants to correlation functions
 
 
Title: Applications of Pade approximants to correlation functions
Author: Paul, R.
Appeared in: Molecular physics
Paging: Volume 41 (1980) nr. 1 pages 1-17
Year: 1980-09
Contents: In this paper we have presented a general scheme whereby the method of Pade approximants may be applied to the power series expansion of time dependent correlation functions. It has been demonstrated by actual numerical calculations, using the computer simulated results of Berne and Harp [5], that even a few terms in the power series expansion are capable of reproducing the correlation curves to a fairly large extent. It is pointed out that the method can be extended to higher orders without the introduction of fitting parameters, and without violating the time parity requirements of the Liouville equation. In the final analysis the method is a truly microscopic method since it relies on the microscopic hamiltonian, and the underlying principles are very straightforward. The basic requirements are the spectral moments, but we do not need many of these as the Pade approximants are highly convergent.
