Effect of Spin Polarization in Nonlinear Parametric Interaction in Magnetized Quantum Plasmas

In the present paper, the spin effect in parametric amplification and dispersion characteristics are determined by implementing the Quantum Magnetized Hydrodynamic (QMHD) model. The QMHD model is extended for spin dynamics, and the spin effect is investigated in a n-type InSb semiconductor plasma. We have determined that the second-order susceptibility resulting from the nonlinear induced current density is the source of the parametric amplification and dispersion characteristics. The study shows that the parametric process is modified by including the quantum effect, especially the spin effect in the formulation. Furthermore, the results indicate that the spin effect can significantly alter the nonlinear optical response of materials, making it an important consideration in the design and optimization of nonlinear optical devices. The findings obtained from this study can be useful in designing and optimizing semiconductor devices for various quantum applications, such as sensors and actuators. Present study provides a deeper understanding of the fundamental quantum plasma physics behind the nonlinear optical response of materials.
