Assuming a logarithmic interaction between constituent particles, compact andlocally accurate wave functions that describe bound states of the two-particleneutral and three-particle charged complexes in two dimensions are designed.Prime examples of these complexes are excitons and trions that appear inmonolayers of Transition-Metal DichalCogenides (TMDCs). In the case ofexcitons, these wave functions led to 5-6 correct decimal digits in the energyand the diamagnetic shifts. In addition, it is demonstrated that they can beused as zero-order approximations to study magnetoexcitons via perturbationtheory in powers of the magnetic field strength. For the trion, making acomparison with experimental data for concrete TMDCs, we established that thelogarithmic potential leads to binding energies $\lesssim 25\%$ greater thanexperimental ones. Finally, the structure of the wave function at smalldistances is established for excitons whose carriers interact via theRytova-Keldysh potential.
