Carnot efficiency and zero-entropy-production rate do not guarantee reversibility of a process
Jae Sung Lee, Sang Hoon Lee, Jaegon Um +1
Thermodynamic process at zero-entropy-production (EP) rate has been regarded as a reversible process. A process achieving the Carnot efficiency is also considered as a reversible p…

Nonuniversality of heat engine efficiency at maximum power
Sang Hoon Lee, Jaegon Um, Hyunggyu Park
We study the efficiency of a simple quantum dot heat engine at maximum power. In contrast to the quasi-statically operated Carnot engine whose efficiency reaches the theoretical ma…
