Foundations of Statistical Mechanics and Quantum Correlations
Abstract
In this project, we studied the equilibration of isolated quantum systems and the effects of quantum correlations in quantum engines using two baths or quantum measurements. In particular, we obtained bounds for the equilibration time of isolated quantum systems and related this to well know speed limit bounds. We then studied how to emulate the dynamics of isolated quantum systems using the propagation of a laser after passing through aperiodic diffracting structures. We also studied how equilibration changes when we prepare initial states whose initial magnetization has low resolution. Concerning quantum engines, we studied magnetic quantum engines and how the coupling between the spins may change the behavior and efficiency of the engine and the role of non-adiabatic driving of the engine. Thus we analyzed the possibility to implement it using dinuclear metal complexes. Finally, we studied the effects of coupling in quantum measurement engines. In total, the results were published in 6 articles in International Journals and one manuscript that is under review. Four post-docs, one Ph.D. student, one master's student, and one undergrad student participated and were financed by the project.
