We study the two-dimensional gas of charged bosons interacting via
a logarithmic potential within the quantal hypernetted-chain
approximation. The pair correlation function, the static structure
factor, the ground-state energy, and the spectrum of collective
excitations are calculated over a range of the density parameter
rs. We find that the static and dynamical properties are
described rather well in this approach in comparison to previous
theories. Our results are in good agreement with the available
quantum Monte Carlo simulations.
