Abstract

This research proposal concerns a one year visit of Prof. Landi to the group of Prof. Goold at Trinity College, Dublin. The two groups already have several common research interests and have been active collaborators for over a year. The goal of this proposal is to consolidate a recently opened front of collaborative research dealing with the connection between thermodynamic uncertainty relations and fluctuation theorems. These are topics which are central to stochastic and quantum thermodynamics and have seen a boom of interest in recent years. Our focus will be on addressing the role of quantum coherent environments in the fluctuations of nanoscale devices, something which may have a direct impact on the implementation of autonomous engines. In pursuing these goals, we will also work towards the development of novel theoretical and numerical techniques for dealing with open quantum systems. Both groups already share the common drive for carrying out interdisciplinary research at the boundary between condensed matter, quantum information and statistical mechanics. However, we usually approach these problems using different, complementary, routes. We plan to dedicate substantial time to the exchange of knowhow on the different methods, strengthening already known techniques and developing brand new ones. This will be vital for maintaining both groups at the forefront of quantum thermodynamics, with long-term benefits to both groups and institutions.
