- 論文の詳細を見る
The longitudinal and transverse collective modes are studied in liquid silver chalcogenides by making use of a hydrodynamic description. The effect of deviation from the stoichiometric composition is studied over a wide range of concentrations. The result reveals the existence of coupled collective modes. It is shown that the frequency gap at the crossing point of the modes decreases with the decrease in the relaxation time. An approximate analytical solutions for both, longitudinal and transverse modes are obtained. It is also shown that the analytical solutions for large value of the deviation from stoichiometry agree with the exact numerical solution.
