Abstract

The dynamics of entropy exchange and correlation inu(2)algebraic model for two stretches ofH2OandSO2is studied in terms of the linear entropy with diagonal approximation, where various initial states are respectively taken to be the product of thermal states and squeezed states on each mode. It is shown that with a suitable parameter in initial states, the entropies in each stretch are positively correlated or anticorrelated, which depend on initial states and a molecule. The entropy correlation is also studied in terms of a correlation index. It is demonstrated that the correlation index and the sum of linear entropies in each stretch are identical in oscillation. The differences in the linear entropy in each stretch and the correlation index of the thermal states and the squeezed states betweenH2OandSO2are noticed. These may be useful for quantum computing and quantum information processing based on two stretching modes in both molecules.
