Anisotropy parabolic potential (APP) effects on ground state (GS) energy E0 and the vibration frequency (VF) λ of weak-coupled magnetopolaron (MP) in asymmetric Gaussian quantum wells (AGQWs) were investigated using the linear combination operator and unitary transformation method. The obtained results showed that E0 and λ were increased by increasing the barrier height V0 of AGQWs as well as transverse and longitudinal confined strengths ωx and ωy of APP and decreased with increase in the asymmetric Gaussian confinement potential (AGCP) range R and transverse and longitudinal effective confined lengths lx and ly of APP. Thus, the GS energy and VF of MP could be changed by adjusting the confinement parameters of the APP and AGCP. The study of quantum wells’ semiconductor materials has broad potential applications in semiconductor lasers, optoelectronic devices and quantum information.
