Sh. Kim et al., REENTRANT TRANSITIONS IN GLOBALLY COUPLED ACTIVE ROTATORS WITH MULTIPLICATIVE AND ADDITIVE NOISES, Physics letters. A, 224(3), 1997, pp. 147-153
We study the nonequilibrium phenomena in globally coupled active rotat
ors with multiplicative and additive noises, It is shown that at a cri
tical value of the multiplicative noise intensity the system undergoes
noise-induced transition from a one-cluster state to a two-cluster st
ate, Additive noise suppresses the effect of the multiplicative noise
on the system, increasing the critical value of the multiplicative noi
se intensity, The system shows a reentrant transition at intermediate
additive noise intensity.
