Additional recruitment to the Doctoral School of Exact Sciences beyond the limit of places

Project description:      

Transport properties of correlated hybrid nanostructures, involving molecules and atoms as well as their artificial counterparts, coupled to external contacts are the subject of extensive theoretical and experimental studies not only due to various fundamental aspects and new physical phenomena, but also because of possible applications in nanoelectronics and quantum technologies for storing and processing information. However, to further progress the development of quantum technologies or to propose any working device, it is of crucial importance to fully understand the system’s behavior under different conditions, involving both equilibrium and out-of-equilibrium situations as well as the stationary and transient regimes. In this regard, a special attention has been recently paid to the time-dependent phenomena and dynamical quantum critical behavior triggered upon a controllable change of the system’s parameters, referred to as quantum quench, which may lead to dynamical phase transitions - a counterpart of phase transitions but taking place in the time domain. The main goal of this project is therefore to search for signatures of dynamical quantum criticality, shed new light and provide accurate predictions for the dynamical and transport behavior of correlated hybrid nanostructures, involving, among others, superconducting reservoirs interacting with quantum impurities, such as adatoms, quantum dots or molecules. This will enable the extension of the concept of dynamical phase transitions, which so far have been mainly studied in the case of global parameter changes, to mesoscopic systems, where local quenches can be performed in a fully controllable fashion. Furthermore, it will pave the way towards controllable investigation of time-dependent phenomena in nanoscale systems and obtain predictions for models that are relevant in a broader context of condensed matter physics. In particular, the systems planned to be studied within this project in the context of (time-dependent) transport and dynamical phase transitions involve among others large-spin molecules or multi-level quantum dots interacting with superconducting reservoirs as well as hybrid artificial molecules or multiple quantum dot systems, which enable the realization of the Yu-Shiba-Rusinov molecules, dimers or trimers. The considerations will be based upon very accurate numerical methods, such as time-dependent numerical renormalization group method, which will be appropriately adapted and extended to the case of studied systems and problems, such as multiple quench dynamics or calculations of various correlation functions in the time domain. The assumed methodology and numerical tools allow for obtaining high-quality quantitative results with all the correlations and interactions taken into account in an essentially exact manner. Thus, the planned investigations and calculations will provide reliable results for the time-dependent and transport phenomena that will be of relevance to both theoretical and experimental works. Moreover, our theoretical predictions shall foster further investigations of physical properties of hybrid nanoscale systems and devices .
