Energy and information flows in autonomous systems
Jannik Ehrich, David A. Sivak
Multi-component molecular machines are ubiquitous in biology. We review recent progress on describing their thermodynamic properties using autonomous bipartite Markovian dynamics.…
Information engine in a nonequilibrium bath
Tushar K. Saha, Jannik Ehrich, Momčilo Gavrilov +3
Information engines can convert thermal fluctuations of a bath at temperature into work at rates of order per relaxation time of the system. We show experimenta…
Energetic cost of feedback control
Jannik Ehrich, Susanne Still, David A. Sivak
Successful feedback control of small systems allows for the rectification of thermal fluctuations, converting them into useful energy; however, control itself requires work. This p…
Bayesian information engine that optimally exploits noisy measurements
Tushar K. Saha, Joseph N. E. Lucero, Jannik Ehrich +2
We have experimentally realized an information engine consisting of an optically trapped, heavy bead in water. The device raises the trap center after a favorable "up" thermal fluc…
