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…
Relativistic Quantum Otto Engine: Generalized efficiency bounds and frictional effects
Vahid Shaghaghi, Pritam Chattopadhyay, Vijit V. Nautiyal +3
This work investigates a relativistic quantum Otto engine with a harmonic oscillator as its working medium, analyzing how relativistic motion and nonadiabatic driving affect its pe…
Relativistic Quantum Thermal Machine: Harnessing Relativistic Effects to Surpass Carnot Efficiency
Tanmoy Pandit, Pritam Chattopadhyay, Kaustav Chatterjee +1
We investigate a three-level maser quantum thermal machine in which the system-reservoir interaction is modeled via Unruh-DeWitt type coupling, with one or both reservoirs undergoi…
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…
