Optimal operation of a three-level quantum heat engine and universal nature of efficiency
Varinder Singh
We present a detailed study of a three-level quantum heat engine operating at maximum efficient power function, a trade-off objective function defined by the product of the efficie…
Optimal Performance of a Three-level Quantum Refrigerator
Varinder Singh, Tanmoy Pandit, Ramandeep S. Johal
We study the optimal performance of a three-level quantum refrigerator using two different objective functions: cooling power and -function. For both cases, we obtain general ex…
Low-dissipation Carnot-like heat engines at maximum efficient power
Varinder Singh, Ramandeep S. Johal
We study the optimal performance of Carnot-like heat engines working in low dissipation regime using the product of the efficiency and the power output, also known as the efficient…
Feynman-Smoluchowski engine at high temperatures and the role of constraints
Varinder Singh, Ramandeep S. Johal
Feynman's ratchet and pawl is a paradigmatic model for energy conversion using thermal fluctuations in the mesoscopic regime. Here, we optimize the power output of the ratchet as a…
