Observation of Feigenbaum period-doubling bifurcations in an MHD instability of an electron-hole plasma in bismuth
Kopylov V. N., Yanchenko S. S.
As the direct current through a bismuth sample is increased, the carrier flux becomes unstable, and the period of the electromagnetic waves emitted by the sample goes through a sequence of doublings. The observed results agree with Feigenbaum's model.
