Variational-integral perturbation corrections of some lower excited states for hydrogen atoms in magnetic fields

Abstract: A variational-integral perturbation method (VIPM) is established by combining the variational perturbation with the integral perturbation. The first-order corrected wave functions are constructed, and the second-order energy corrections for the ground state and several lower excited states are calculated by applying the VIPM to the hydrogen atom in a strong uniform magnetic field. Our calculations demonstrated that the energy calculated by the VIPM only shows a negative value, which indicates that the VIPM met… Show more

“…In the present study, applying the improved Rayleigh-SchrΓΆdinger perturbation theory based on an integral equation to helium-like ions in ground states and treating electrons as perturbations, [33,34] we employ the improved variational-perturbation method (VIPM) based on the integral equation to solve the heavy quarkonium in the 2𝑆 state. [35] We apply the VIPM to the hydrogen atom in a strong and uniform magnetic field, [36] construct corrected wave functions and calculate energy corrections for ground state and some excited states such as 4𝑑2, 4𝑑1, 4𝑑0, 4𝑑.1, 4𝑑.2, 4𝑓 3, 4𝑓 2, β€’ β€’ β€’. These values are compared with those of the elaborate calculations of Smith et al [10] and the simple basis variational calculations of Jason.…”

“…Perturbation theory is widely used for solving a SchrΓΆdinger equation that has no exact analytical solution. [1][2][3][4][5][6] It is well-known that the accuracy of the calculated energies from perturbation theory depends on the magnitude of the perturbation term in the Hamiltonian of the SchrΓΆdinger equation. Recently, Zhang et al [7,8] proposed a parameter perturbation method to minimize the influence of the perturbation term and this method gives a good estimate of the ground-state energy for the helium-like atom.…”
