In numerical simulations ranging\r\nfrom the quasi-collisionless case to the hydrodynamic regime, we find that the\r\nonset of $v_n$ and of related measures of anisotropic flow can be described\r\nwith a simple power-law ansatz, with an exponent that depends on the amount of\r\nrescatterings in the system. In the few-rescatterings regime we perform\r\nsemi-analytical calculations, based on a systematic expansion in powers of time\r\nand the cross section, which can reproduce the numerical findings."}],"date_created":"2022-06-27T09:08:04Z","status":"public","external_id":{"arxiv":["2201.13294"]}}
