| 内容記述 | In this thesis, I present the work I did in my PhD in the field of quantum thermodynamics. The aim of this work is to explore quantum engines that can exploit the great tunability of cold atomic systems as the working medium. The thesis is divided into two parts. In the first part, I study the thermodynamics of one-dimensional interacting systems to use them for designing quantum engines. It consists of two research projects. In the first project, I explore anomalous heat flows between two strongly correlated particles and discuss the perspective of using it to realize a quantum fridge. In the second project, I study a quantum heat engine where the work extraction is assisted by changing the interaction within the working medium. In the second part of my thesis, I focus on controlling open quantum systems for optimizing the performance of quantum engines. The quantum Brownian motion has been used to test the different methods. This part consists of two projects, where in the first one, I realize a shortcut to equilibration protocol in a driven open quantum system. For that I propose two different methods. The first one consists of mapping the dynamics of the quantum Brownian motion to an effective stochastic dynamics of an isolated particle. The second methods consists of doing the shortcut protocol by reverse engineering a time-dependent master equation, which was derived by using the Lewis-Riesenfeld invariant. Finally in the second project, I use optimal control methods to speed up the thermalization in isochoric strokes. I also derive a speed limit that predicts the timescale at which the optimal control fails. All projects significantly contribute to the understanding and control of quantum engines. | |||||||
