Abstract

The two-dimensional Yukawa system confined by the parabolic potential at low temperatures was analyzed by numerical simulations and variational calculations. When the number of particles is large, numerical results for the one-body distribution are expressed by a simple interpolation formula. When the screening length is larger than the radial system size, the one-body distribution at low temperatures obtained by numerical simulations is reproduced by minimizing the total energy of the system within the local density approximation.
