Abstract
In chapter 3, the numerical techniques which have been exploited for solving Gross–Pitaevskii (GP)-type equations have been explored in detail. In particular, the algorithmic approaches employed in split-step Crank–Nicolson method, split-step Fourier transform method and Newton conjugate gradient method have been outlined. A glimpse of generating ground states of Bose–Einstein condensates using data driven approaches employing Gaussian processes as an alternative to numerical methods is shown.
