TALISES (This Ain't a LInear Schrödinger Equation Solver) is an easy-to-use C++ implementation of the Split-Step Fourier Method, for numeric calculation of a wave function's time-propagation under the Schrödinger equation.

Features

• the wave-function \(\Psi\) may include an arbitrary number of internal and external degrees of freedom
• simple implementation of Hamiltonians with time-, position-dependent and nonlinear potentials \(V(\Psi,r,t)\)
• speed of C++, the FFTW and GSL libaries and multithreading

• Momentum transfer in 2D harmonic trap
• Stimulated Raman transitions
• Bose-Einstein condensate collision
