Diffusion Monte Carlo calculations for the ground states of atoms and ions in neutron star magnetic fields
arXiv:0711.4958 · doi:10.1103/PhysRevA.76.032501
Abstract
The diffusion quantum Monte Carlo method is extended to solve the old theoretical physics problem of many-electron atoms and ions in intense magnetic fields. The feature of our approach is the use of adiabatic approximation wave functions augmented by a Jastrow factor as guiding functions to initialize the quantum Monte Carlo prodecure. We calcula te the ground state energies of atoms and ions with nuclear charges from Z= 2, 3, 4, ..., 26 for magnetic field strengths relevant for neutron stars.
