Quantum-boosted functionality in single-molecule transistors

When nanoscale components are incorporated into electronic circuits, the laws of quantum mechanics govern their basic properties. Striking phenomena appear, such as entanglement and quantum interference, and have no classical analogue. The next generation of miniaturized electronics will overcome the limitations of traditional design paradigms by exploiting the novel functionality of the nano. The ultimate nanoelectronics building block -- from which to build quantum devices with advanced functionality, sensitivity, and energy efficiency -- is arguably the single-molecule transistor. In addition to embodying the extreme limit of component miniaturization, molecular electronics could utilize the incredible variety of different molecules provided by nature, exploiting their robust and reproducible chemical complexity. But what new physics can be realized in singlemolecule devices, and how can this be harnessed for novel functionality? Which molecules best fulfill this function? To realize the central goal of rational device design, can we formulate a theoretical framework for understanding single-molecule transistors, and develop computational tools for accurate simulation? In this IRC Laureate project, we address these basic frontier questions, building upon recent theoretical developments of the PI, and working closely with experimental molecular electronics collaborators. In particular, we will focus on the complex interplay between quantum interference due to competing transport pathways through a molecule, and entanglement from electronic interactions. We will formulate a rigorous strategy for mapping strongly interacting molecular devices to reduced models amenable to treatment with state-of-the-art numerical techniques.

Postdoc position available

Applications are invited for a level 2 postdoctoral position in condensed matter theoretical physics, to join the Theoretical Nanoelectronics Group led by Dr Andrew Mitchell in the School of Physics at University College Dublin. The position is funded through the prestigious 'Laureate' programme of the Irish Research Council, for 2 years in the first instance, and with funding in place for renewal for a further 2 years. The project concerns quantum transport through single-molecule junctions, especially those in which strong electron interactions and/or quantum interference effects play a key role. The successful applicant will have a PhD in quantum condensed matter theory, with experience of quantum transport in nanostructures, simulation, or strongly correlated quantum systems. The group benefits from existing collaborations with leading experimental groups. Generous funding is available for equipment and travel.

PhD position available

A fully-funded PhD position (stipend plus fees at EU level) is available in the Theoretical Nanoelectronics Group led by Dr Andrew Mitchell in the School of Physics at University College Dublin, to work on the above project. The topic of the project is broadly the theory of molecular electronics devices, and specifically the theory and simulation of single-molecule transistors, taking into account both molecular structure and strong electron interactions. The fronteir basic research will be applied to the rational design of new nanoscale components with advanced quantum functionality. The successful applicant will have a Masters degree in theoretical physics, and an interest in condensed matter theory. The PhD programme at UCD is 4 years duration, and generous funding is available for equipment and travel.
