In this paper, a non-linear (3+1)-dimensional Zakharov-Kuznetsov equation is
investigated by employing the subsidiary equation method, which arises in
quantum magneto plasma. The periodic solutions, rational wave solutions,
soliton solutions for the quantum Zakharov-Kuznetsov equation which play an
important role in mathematical physics are obtained with the help of the
Riccati equation expan?sion method. Meanwhile, the electrostatic potential
can be accordingly obtained. Compared to the other methods, the exact
solutions obtained will extend on earlier reports by using the Riccati
equation.
