Rapid optimal work extraction from a quantum-dot information engine
Kushagra Aggarwal, Alberto Rolandi, Yikai Yang +8
The conversion of thermal energy into work is usually more efficient in the slow-driving regime, where the power output is vanishingly small. Efficient work extraction for fast dri…
