Lay Abstract:

Quantum technology, rooted in the principles of quantum physics, holds immense promise for revolutionizing our future. By harnessing quantum principles, it promises to vastly improve the efficiency of various technologies, from batteries to computers. Classical heat engines operate by converting heat into work through a series of "strokes." Similarly, there's a growing interest in developing quantum devices, known as Quantum Heat Engines, that leverage purely quantum features to outperform classical devices. This project focuses on understanding how atomic interactions impact the performance of QHEs and aims to optimize their efficiency .

Scientific Abstract:

Quantum heat engines (QHEs) perform a thermodynamic cycle employing quantum systems as the working medium. QHEs allow one to explore the limits and possibilities of quantum thermodynamics. The project aims to explore quantum thermodynamics by examining quantum heat engines utilizing interacting ultracold atoms. It spans from weakly interacting Bose-Bose mixture condensates to intermediate finite coupling Bose gases and strongly correlated atomic systems. The project delves into the impact of interactions, both weak and strong, repulsive and attractive, on the performance of QHEs. Additionally, it seeks to develop extended Shortcut to Adiabaticity methods to optimize the balance between efficiency and power output in finite-time engine cycles. Concurrently, it investigates the influence of temperature-dependent dynamics in Bose gases or Tonks-Girardeau gases on QHE performance. Through theoretical inquiries and collaborations, this project introduces an innovative paradigm with profound implications for energy efficiency and quantum technologies.
