摘要：
This note examines Gross-Pitaevskii equations with PT-symmetric potentials of the Wadati type: V = -W-2 + iW(x). We formulate a recipe for the construction of Wadati potentials supporting exact localised solutions. The general procedure is exemplified by equations with attractive and repulsive cubic nonlinearity bearing a variety of bright and dark solitons.
