Abstract
In this paper, we consider positive oscillator-shaped well potential and set a Szilard-like quantum heat engine based on energy level degeneracy. By using position-dependent energy eigenvalues of the oscillator-shaped well, we compute extracted work and efficiency based on Stirling-like thermodynamical cycle. We obtain numerical results for physical quantities and discuss work and efficiency dependence of angular frequency, well width, and temperature.
期刊介绍：
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
