摘要
<jats:sec><jats:label /><jats:p>We present a Wigner signed particles analysis of the lense‐governed electron state dynamics based on the quantitative theory of coherence reformulated in phase space terms. Electrostatic lenses are used for manipulating electron evolution and are therefore attractive for applications in novel engineering disciplines like entangletronics. The signed particle model of Wigner evolution enables physically intuitive insights into the processes maintaining coherence. Both, coherent processes and scattering‐caused transitions to classical dynamics are unified by a scattering‐aware particle model of the lense‐controlled state evolution. Our approach bridges the fairly new theory of coherence with the Wigner signed particle method.</jats:p></jats:sec>
