  Non-Equilibrium Steady-States of Quantum many body systems (QuamNESS)
  Summary

  Quantum thermodynamics is an emerging and expanding field that is experiencing a remarkable growth in output. Important progress is still needed before it can impact significantly on the technological and industrial sector. QuamNESS will contribute to narrowing this knowledge gap by providing an innovative and powerful platform that combines powerful numerics with advanced theoretical tools. Crucially, this mixture of methodologies is both fundamental and practical in nature. The proposed project will deepen our understanding of the conceptual building blocks of quantum thermodynamic processes at the smallest scales at the frontier of future technologies. It will also build sophisticated numerical methods for accurately tracking of the properties of increasingly complex systems relevant for the engineering of real nano-scale devices. The project therefore represents the first systematic merging of these two perspectives within the burgeoning field of quantum thermodynamics. Such a novel combination will spur new analyses of non-equilibrium physics, previously prevented by the inherent difficulty of simulating complex quantum systems and lack of clarity in how to quantify their functional behaviour. By realizing its objectives, QuamNESS will thus make a substantive impact in our understanding of non-equilibrium steady states in the quantum regime, with immediate benefits for the broadest quantum community. In particular, QuamNESS's deliverables are of relevance for nanotechnology, chemistry, biology and, potentially, industrial applications in magnetic materials and memory devices. At the same time the project will help identify further challenges in the design of quantum devices and will lay the foundations of new thermodynamically inspired approaches.

  ODYSSEY-Open dynamics of interacting and disordered quantum systems
  Summary

  This research proposal focuses on the open quantum system dynamics of disordered and interacting many- body systems coupled to external baths. The dynamics of systems which contain both disorder and interactions are currently under intense theoretical investigation in condensed matter physics due to the discovery of a new phase of matter known as many-body localization. With the experimental realization of such systems in mind, this proposal addresses an essential issue which is to understand how coupling to external degrees of freedom influences dynamics. These systems are intrinsically complex and lie beyond the unitary closed system paradigm, so the research proposed here contains interdisciplinary methodology beyond the mainstream in condensed matter physics ranging from quantum information to quantum optics. The project has three principal objectives each of which would represent a major contribution to the field: 1. To describe the dynamics of a interacting, disordered many-body systems when coupled to external baths. O 2. To perform a full characterization of spin and energy transport in their non-equilibrium steady state. 3. To explore the system capabilities as steady state thermal machine from a systematic microscopic perspective. This will be the first comprehensive study of the open system phenomenology of disordered interacting many-body systems. It will also allow for the systematic study of energy and spin transport and the exploration of the potential of these systems as steady state thermal machines. In order to successfully carry out the work proposed here, the applicant will build a world class team at Trinity College Dublin. Due to his track record and interdisciplinary background in many-body physics, quantum information and statistical mechanics combined with his personal drive and ambition the applicant is in a formidable position to successfully undertake this task with the platform provided by this ERC Starting Grant.

  Thermodynamic potential of disordered quantum wires
  Summary

  Thermodynamics is a theory with an impressive range of applicability, successfully describing the properties of macroscopic systems ranging from refrigerators in your kitchen to black holes in the universe. With the the industrial and electronic revolutions behind us, we are currently pushing technology towards and beyond the microscopic scale to the border of where quantum mechanical effects prevail. Currently, there is a large interest in the quantum information, quantum optics and statistical mechanics communities surrounding the thermodynamic description of non-equilibrium quantum systems from both a fundamental and applicative view point. Central to this interest is the concept of the quantum thermal machine. These are machines which convert heat to work at the nanoscale level and are expected to play an increasingly central role in emerging quantum technologies. A highly relevant and well studied example of such machines, in the classical and quantum domain, are thermo-electrics. A thermoelectric device is one which converts heat to electrical energy, but is different to other thermal devices- in that it does not have moving parts such as pistons or gears. In thermo-electrics - steady state electrical currents can be made flow in the presence of a thermal gradients and vice versa. This is why they are sometimes known as steady state devices. Despite the progress made in the last years, the efficiency of such devices remains too low to be competitive with other technologies and there is no clear consensus what are the microscopic components which lead to good thermoelectric efficiencies. This research focuses on understanding how the fundamental microscopic features of a material, containing the inevitable ingredients of disorder, interactions and dephasing, could give rise to favourable thermal expectation values which would boost both power and efficiency of a steady state thermal device which uses that material as a working medium.

  Thermodynamics for Quantum Technologies
  Summary

  When considering devices operating at a scale where quantum mechanical laws become important we may ask whether the solid grounds of thermodynamics might be challenged, not only by the lack of a thermodynamic limit, but also by the intrinsic uncertainty synonymous with this domain. It comes as no surprise that there has been a recent concerted effort to understand how the laws of thermodynamics generalize to arbitrary quantum systems both at and away from equilibrium. This effort is known as quantum thermodynamics and its development and application is the subject of this proposal. Specifically I will develop and apply thermodynamic concepts to finite size quantum systems in generically non equilibrium settings. By combining well developed tools of condensed matter physics, quantum information and quantum optics with quantum thermodynamics approaches I plan to model the physics of both single and many-body quantum devices and systems at and far from thermodynamic equilibrium. Specifically the research is focused on the description, development and optimization of stochastic quantum engine cycles, developing concepts in quantum thermodynamics to understand the thermodynamic efficiency of quantum information processing and in addition to explore the emergence of thermodynamic behavior from the underlying complex dynamics of many-body systems.The research outlined will enhance our understanding of the fundamental limitations of future technologies, generate the blueprints for a new class of optimized nano-machines, lead to the new design of efficient controls for thermal machines and enhance our understanding of non equilibrium quantum dynamics.

  ICARUS - Information Content of Localisation: From classical to quantum systems
  Summary

  The aim of this proposal is to study quantum dynamics in the presence of disorder, and specifically the Anderson and many- body localization transition to a phase where transport and thermalization are absent. Localization in quantum systems has both deep fundamental implications in many different fields and exciting practical applications in quantum technology. In this action the researcher, who is experienced in the statistical physics of quantum disordered systems, will address in a novel and timely way this topic. She aims to improve understanding of it with a three-fold approach: a quantum information experimental effort; new theoretical tools coming from the study of random matrices and the physics of glassy systems; and a joint work with a non-academic entity on numerical methods that use artificial neural networks for the classification of the localized phase. She will perform this work in the perfectly suited environment of the Thermodynamics and Energetics of Quantum Systems research group at Trinity College Dublin.

  PREB-Open Quantum Dynamics via Periodically Refreshed Baths
  Summary

  PReB: open quantum dynamics via Periodically Refreshed Baths is a research proposal with two ambitious goals: (a) develop a theory to numerically exactly describe quantum dissipative many-body systems under a constant or time dependent voltage/temperature bias, (b) use the theory to explore quan- tum thermodynamics of such systems. This requires combining fundamental concepts from condensed matter physics with those from open quantum systems and incorporating these into state-of-the-art nu- merical techniques for many-body dynamics. PReB seeks to provide a widely applicable go-to numerical technique for exploring, understanding and benchmarking noisy quantum devices.

  Shortcut-enhanced quantum thermodynamics
  Summary

  We are currently at the beginning of a second quantum revolution: With technology developments reaching smaller and smaller scales, quantum effects must be taken fully into consideration. Such new quantum technologies are already emerging, e.g., quantum cryptography and quantum simulations for drug design. Nevertheless, the realization of quantum technologies which is beyond the proof-of-principle state and which fully utilize the potential of quantum mechanics remains a major challenge because of the fragile nature of quantum states. There is a strong need for understanding and controlling many-particle complex systems at the quantum level. The key idea of this project is to combine shortcuts-to-adiabaticy and quantum thermodynamics to design a new route for solving these challenges. The potential for this merging is nearly self-explaining: ideal thermodynamic processes are based on adiabatic processes which give maximal efficiency but unfortunately require infinite operation time; on the other hand, shortcuts-to-adiabaticy are techniques to speed-up adiabatic processes. Having leading expertise in Ireland in both of these research fields naturally motivates to this proposal. The achieved knowledge will be also used to design new energetically efficient quantum technologies.

  Complex Quantum Thermal Machines
  Summary

  The central goal of this project is to take a powerful numerical technique known as matrix product operators and apply the technique to computationally model the basic physics of a class of quantum thermal machines. So, in addition to a significant fundamental scientific component, this research project also promises to develop new computational tools that can be applied to a range of existing architectures, working towards the ultimate goal of machine optimisation.
