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…

Three heats in strongly coupled system and bath
Chulan Kwon, Jaegon Um, Joonhyun Yeo +1
We investigate three kinds of heat produced in a system and a bath strongly coupled via an interaction Hamiltonian. By studying the energy flows between the system, the bath, and t…

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…
