Group description
We develop a theoretical activity on quantum transport, nano- and opto-mechanical systems, molecular electronics, and topological quantum systems. We are particularly interested to carbon nanotube mechanical resonators, fluctuations (current-noise, fullcounting statistics, squeezing), hybrid normal/superconducting systems, Josephson junctions, quantum coherence, quantum technologies, plasmonic nanojunctions, polaritonic chemistry, impurity physics, and topological quantum effects in electronic systems.

ADVANCED MATERIALS AND PROCESSES
Electronic Transport and light-emission through Molecules in Plasmonic Nanocavities
- We explore from theoretical point of view the physics of light-emission in plasmonic nano-cavities and scanning tunneling microscopes (STM). We aim at achieving a full quantum-mechanical model of the plasmonmolecule coupling in the STM cavity, taking into account dissipation by the environment and driving by an external laser, that are both crucial features in plasmonics experiments. We develop new theoretical tools, in order to achieve a qualitative understanding of the strong-coupling regime between molecules, electronic tunneling currents, and plasmonic fields. The main outcome would be to open new perspectives towards quantitative molecular simulations, and shining light on debated issues, like knowing which mechanism is relevant for understanding the lightemission process in experiments. Such knowledge is indeed crucial to design and engineer a new generation of electrically-controlled singlephoton sources based on the use of STM-tips.

- Topological materials exhibit robust electronic properties that enable a deeper understanding of matter phases and potentially offer fascinating applications. While exhaustive databases of such materials have just been predicted through the paradigm of Topological Quantum Chemistry, a decisive step is now to relate their topological nature to ubiquitous observables routinely resolved in experiments.
- In this context, we investigate impurity scattering as a novel route. We indeed showed that specific impurities can reveal the topological nature of some materials through the fluctuations of electronic density. We now aim at generalizing this approach to all nontrivial materials. This consists of extending the exhaustive space-symmetry group analysis of topological quantum chemistry to quantum scattering theory, and so identify universal symmetry selection rules indicating the band structure topology. This would result in an exhaustive catalog of the impurities that can reveal the recently databased nontrivial materials through the electronic density, for instance in scanning tunneling microscopy experiments.
Quantum Information with nanomechanical oscillators
- We recently published a paper on how a nanomechanical oscillator could be used to form a qubit well protected from the decoherence induced by the environment. We are investigating how this kind of systems can be coupled and how they can be used as quantum simulators to study the phonon-electron interaction, that plays a crucial role in superconductivity. (cf. our recent pre-print Phonon-induced pairing in quantum dot quantum simulator, U. Bhattacharya, T. Graß, A. Bachtold, M. Lewenstein, F. Pistolesi, arXiv:2106.09418)
The research group has a history of scientific collaboration with the research group of Thomas Frederiksen, in the University of the Basque Country (UPV/EHU), and the Donostia International Physics Center (DIPC). Rémi Avriller, Fabio Pistolesi and Thomas Frederiksen are indeed active partners of the Transnational Common Laboratory “QuantumChemPhys – Theoretical Chemistry and Physics at the Quantum Scale”, an international collaborative framework built between University of Bordeaux, the University of the Basque Country (UPV/EHU), and the Donostia International Physics Center (DIPC). In the framework of the LTC “QuantumChemPhys”, they have recently co-directed the PhD thesis of Quentin Schaeverbeke (2016-2020) entitled « Photon emission and quantum transport in nanoplasmonic cavities ». This thesis was financed half by the international PhD program of UBx IDEX and half by the DIPC. It enabled to build a strong collaboration between the partners on the topics of electronic transport in plasmonic cavities. One paper has been published in Physical Review Letters out of this collaboration: Q. Schaeverbeke, R. Avriller, T. Frederiksen and F.
Pistolesi, “Single-photon emission mediated by single-electron tunneling in plasmonic nanojunctions”, Phys. Rev. Lett. 123, 246601 (2019).
