| Research Abstract |
We succeeded to demonstrate the first realization of a Szilard-type Maxwell’s demon. We performed a nonequilibrium feedback manipulation of a Brownian particle based on information about its location achieves information-energy conversion. Moreover, a new nonequilibrium equality concerning the feedback control has been shown to hold. Furthermore, we realized self-propelling Janus particles by defocused laser irradiation. We found that the motion is caused by self-thermophoresis: i.e. migration due to a local temperature gradient induced by laser heating at the metal coated side of the Janus particle.
