Dataset for noncentral collisions of two-dimensional logarithmic quantum droplets: momentum-controlled transition from capture to scattering.

This dataset contains the diagnostic time series, summary tables, and figures supporting the manuscript “Noncentral collisions of two-dimensional logarithmic quantum droplets: momentum-controlled transition from capture to scattering.” The simulations solve a dimensionless logarithmic Gross--Pitaevskii equation using a split-step Fourier method. Base collision scans were performed for (k_0=0.25), (0.50), and (0.75), with impact parameters (b=0.0), (0.5), (1.0), (1.5), and (2.0).

The data support a preliminary regime map showing quasi-elastic scattering, delayed separation, and a long-lived captured oscillatory state. A refined validation of the captured state at (k_0=0.25), (b=2.0) is included up to (t=80), using (L=48), (N_x=N_y=512), and (\Delta t=2.5\times10^{-4}).
