Thermodynamics of continuous non-Markovian feedback control

The second law of thermodynamics cannot be straightforwardly applied to systems with non-Markovian feedback control, and previous extensions to cover that regime have not been tested experimentally. Here, the authors bridge this gap using an optically levitated microsphere in a feedback-cooling syst...

Sumario:The second law of thermodynamics cannot be straightforwardly applied to systems with non-Markovian feedback control, and previous extensions to cover that regime have not been tested experimentally. Here, the authors bridge this gap using an optically levitated microsphere in a feedback-cooling system.
