【 摘 要 】
We investigate the quasi-exact solutions of an analogous Schrödinger wave equation for two-dimensional non-Hermitian complex Hamiltonian systems within the framework of an extended complex phase space characterized by ð‘¥ = ð‘¥1 + ð‘–ð‘3, 𑦠= ð‘¥2 + ð‘–ð‘4, ð‘ð‘¥ = ð‘1 + ð‘–ð‘¥3, ð‘𑦠= ð‘2 + ð‘–ð‘¥4. Explicit expressions for the energy eigenvalues and eigenfunctions for ground and first excited states of a two-dimensional $mathcal{PT}$-symmetric sextic potential and some of its variants are obtained. The eigenvalue spectra are found to be real within some parametric domains.
