Webdiscrete truncated Wigner approximation (DTWA) [10] { has been developed. In the DTWA, the many-body dy-namics of spin-1 2 systems is described by a set of classical equations of motion of the Cartesian spin components, while interactions are accounted for at the mean- eld level. Similar to the truncated Wigner approach to Bose elds [11{14 ...
