Collective motion of active particles in environmental noise
《Chinese Physics B》2017年第9期565-570,共6页陈秋实 季铭 
Project supported by the National Natural Science Foundation of China(Grant Nos.91427302,91027040,and 11474155);the National Basic Research Program of China(Grant No.2012CB821500)
We study the collective motion of active particles in environmental noise, where the environmental noise is caused by noise particles randomly diffusing in two-dimensional space. We show that active particles in a noi...
