From May 27 to 31, 2024, a series of lectures and seminars (6h), on: Introduction to Machine Learning for Quantum Systems and Materials with Strong Electronic Correlations.
*Under agreement with Collège de France.
During 2016-2017, three lectures on: Theory of Quantum Materials.
From May to June 2015, three lectures on: Quantum engineering of materials and devices with strong electronic correlations.
This year, all lectures took place in Grenoble, at the invitation of the Université Grenoble-Alpes, and the Labex "Alliances - Nanosciences Energies du Futur" (LANEF). The lectures were entitled "Quantum engineering of materials and devices with strong electronic correlations". It was divided into three parts, each comprising three hours of lectures.
The first part, entitled "Introduction to the physics of materials with strong electronic correlations", first introduced some key concepts in the physics of strong electronic correlations, such as Coulomb blocking and the Mott transition. This was followed by a description of the physics of magnetic impurities in metals (the Kondo effect) and their consequences for Coulomb blockade in quantum dot nanoelectronic devices. A third lecture introduced the description of the Mott transition based on dynamic mean-field theory.
The second part, entitled "Heterostructures, light control: towards new oxide functionalities", aimed to describe recent advances in controlling the functionalities of transition metal oxides. After a general introduction to the properties and electronic structure of these materials, we showed how the development of high-quality heterostructures and thin films enables control by stress (in compression or tension), or by doping using ionic liquids, while also enabling the functionalities of several different materials to be combined. The example of RNiO3 nickel oxides was particularly developed, as were recent theoretical advances concerning the metal-insulator transition of these materials. The third lecture dealt with recent developments enabling the structural and electronic properties of materials with remarkable properties (manganites, cuprates, nickelates) to be selectively controlled by Tera-Hertz pulses, the underlying mechanism being anharmonic coupling between optical and Raman phonons ("nonlinear phononics").
Finally, the third part dealt with "Thermoelectric effects: from materials to small quantum systems". A first lecture described the fundamental basics of the field. In a second lecture, the Landauer formalism for mesoscopic thermoelectric transport was introduced, with applications to thermoelectric effects in mesoscopic devices, which have seen a resurgence of interest recently. Finally, the last lecture was devoted to effects coupling particle and entropy transport in cold atomic gases and recent experiments on this subject (in connection with recent contributions from the Chair team, also involving collaboration with the team of T. Esslinger and J.-P. Brantut at ETH).
In May 2014, a series of lectures on: Ernst Robert Curtius Gastprofessur. From Cold Atoms to Quantum Materials
In January 2014, three lectures on: Electronic structure of materials with strong correlations.
During 2012-2013, three lectures and three seminars on: Materials with strong electronic correlations (calculation of the electronic structure of these materials within the framework of dynamic mean field approaches (DMFT)).
On May 20 and 27, 2011, a series of lectures on: Electronic Structure of Correlated Materials from a Dynamical Mean-Field Theory viewpoint: Introduction, State of the Art and Perspectives
Materials with strong electronic correlations have an amazing diversity of physical properties and potential functionalities. This diversity can only be fully grasped by going beyond the simplest model descriptions and taking into account the multiple degrees of freedom (especially orbital ones) and the often-complex electronic structure of those materials. Dynamical Mean-field Theory, in combination with electronic structure methods, has allowed for significant progress towards this goal. After a brief introduction to these approaches, the lectures will aim at providing an overview of their current capabilities, emphasizing successes but also limitations and the need for extensions. The lectures will be illustrated by several examples taken among transition-metal oxides and rare-earth compounds.
