Abstract

Recently we reported experimental test for Fluctuation Theorem in Aharanov‐Bohm ring. In this Paper, we report experimental results to support it. We change electron density in finite magnetic fields. Also in this case, nonequilibrium fluctuation relations based in the Fluctuation theorem are valid. These results provide experimental evidence of the fluctuation theorem in the quantum coherent regime and open up a new way to explore nonequilibrium statistical mechanics.
