Discrete Nonlinear Schrodinger Equations Free of the Peierls-Nabarro Potential
We derive a class of discrete nonlinear Schrödinger (DNLS) equations for general polynomial nonlinearity whose stationary solutions can be found from a reduced two-point algebraic problem. It is demonstrated that the derived class of discretizations cont
