Quench Dynamics in Interacting and Superconducting Nanojunctions

Effects of many-body interactions and superconducting correlations have become central questions in the quantum transport community. While most previous works investigating current fluctuations in nanodevices have been restricted to the stationary regime, Seoane's thesis extends these studies to the time domain. It provides relevant information about the time onset of electronic correlations mediated by interactions and superconductivity. This knowledge is essential for the development of fast electronic devices, as well as novel applications requiring fast manipulations, such as quantum information processing. In addition, the thesis establishes contact with issues of broad current interest such as non-equilibrium quantum phase transitions.

Nominated as an outstanding Ph.D. thesis by the Universidad Autónoma de Madrid, Madrid, Spain Offers a detailed study of quantum transport through nanostructures in the non-stationary regime Explores the time onset of electron correlations mediated by interactions and superconductivity Analyzes the current fluctuations, showing their relation to the phase transition theory
