摘要：
In this paper the Lie symmetry analysis is performed on the quantum Zakharov equations that describe the interaction between Langmuir waves and ion-acoustic waves in an electron-ion dense quantum plasma. The similarity reductions and some exact solutions with the aid of sub-equation method are obtained based on the optimal system of one-dimensional subalgebras for the quantum Zakharov equations. In addition, the conservation laws of the quantum Zakharov equations are also constructed using the direct (multiplier) approach.
