This dataset containes the files of the wave-packet centre-of-mass position in x and y, with different values of external force. The first column in each file corresponds to time in ps, while the second column corresponds to the position (in x or y) in micron. The data was used for fitting in Fig. 1 of the supplementary materials of "Quantum geometric tensor and wavepacket dynamics in two-dimensional non-Hermitian systems", where we chose the position at t=1.25 ps from each file to plot the position against the force, and to fit the curvevs with power laws.
