Violation of kinetic uncertainty relation in maser heat engines: Role of spontaneous emission
Varinder Singh, Euijoon Kwon, Jae Sung Lee
We investigate the kinetic uncertainty relation (KUR)-a fundamental trade-off between dynamical activity and current fluctuations-in two configurations of a maser heat engine. We f…

Quantum Thermodynamics on a limit cycle
Varinder Singh, Euijoon Kwon, G J Milburn
We consider a periodic quantum clock based on cooperative resonance fluorescence at zero temperature. In the quantum case, this system has an exact steady state and the limit cycle…
