Active-Countoscope

This repository contains the codes used in the investigation of self-propelled particles motion using the Countoscope framework.

It includes codes computing $\langle \Delta N^2(t) \rangle$ for ABPs and RTPs at order 1, 2 and 3 in the angular moments expansion (ABPT_RT_hydro, ABP_RT_hydro_expanded and ABP_RT_Order3), as well as computing it by integrating numerically the continued fractions at any order to obtain the Intermediate Scattering Function numerically (Compute_NMSD_from_Continued_Fractions).

It also contains tools to compute simulations of non-interacting ABPs, RTPs and AOUPs, and to count these simulations. These results can then be compared to the theory and fitted using our theoretical predictions.

All the capabilities of the code and their usage with one another are illustrated in the Example.py
