Self-propelling liquid pearls

Liquid pearls are drops that hardly wet their substrate. This situation makes it difficult to control them (control of drops is most often triggered by some property at the solid surface). However, since the pearls minimize both their adhesion and friction, even tiny forces can generate spectacular motion – which we describe in two different contexts : drops on hot plates, and dew drops on cold (...)

Depuis trois ans, la recherche sur l'empreinte environnementale des activités de recherche est en plein essor, notamment grâce à la création du GDR Labos 1point5. Nous présenterons brièvement le fonctionnement et les premiers résultats de cet effort collaboratif. Dans une première partie nous détaillerons la mesure de l'empreinte et les postes déterminants : (...)

Statistical physics for climate sciences : application to wave turbulence, extreme heat waves, and extremes of renewable energy production

Colloquium — 2023-04-24T11:37:07Z

Freddy BOUCHET, LMD-ENS & CNRS
Wednesday, May 10, 2023 1:30 p.m. — ConfIV (E244)
I will discuss several examples where statistical physics and large deviation theory can be useful to solve fundamental problems for the dynamics of the climate system.
The first example will be a theoretical contribution to the kinetic theory of wave turbulence. Wave turbulence plays an important role for atmosphere/ocean physical exchanges and for mixing of the ocean interior. I will explain how large (...)

Quantum Chaos and the Foundations of Statistical Mechanics

Understanding the emergence of the rules of statistical mechanics for an isolated many-body system from an underlying quantum-mechanical microdynamics is a longstanding problem of fundamental physics. Concepts from the theory of quantized classically chaotic systems can be used to resolve at least some of the key issues, and lead to the notion of “eigenstate thermalization” : (...)

Cell biophysics : from phase diagrams to phase portraits - POSTPONED TO SEPTEMBER 2023 !!

Cell functions such as motility and division can be studied with the use of stripped-down experimental systems by choosing carefully a limited number of purified proteins that reproduce cellular behaviours in simplified and controlled conditions. As an example, cytoskeleton dynamics are reproduced on liposome membranes , (Figure 1) and soft matter (...)

Quantum light generation with artificial atoms

Colloquium — 2023-02-08T11:43:10Z

Wednesday, February 15, 2023 1:30 p.m. — ConfIV (E244)
Quantum light is a key ingredient of the emerging second quantum revolution. It is the cornerstone of many applications ranging from quantum computing to quantum networks, offering many degrees of freedom to encode the information. Semiconductor quantum dots are artificial atoms that, over the years, have been shown to be excellent sources of quantum light. In this talk, I will present the (...)

Simulating strongly correlated systems with tensor network algorithms

Colloquium — 2023-01-12T09:14:45Z

Wednesday, January 25, 2023 1:30 p.m. — ConfIV (E244)
One of the biggest challenges in physics is understanding strongly correlated quantum many-body systems, which give rise to very remarkable phenomena such as high-temperature superconductivity or novel states of matter with topological order. Despite the fact that these systems can often be described by simple models on a lattice, it is very difficult to study them, because standard numerical (...)

Quantum many-body physics with ultracold atoms : Sailing the quantum seas

Wednesday, January 11, 2023 1:30 p.m. — Amphi Jaurès (E244)
Understanding the properties of a large number of particles in interaction is one of the frontiers of modern physics : from the stability of sandpiles to the formation of large structures in the universe or the behaviour of complex neural networks, it is at the core of almost all current fields of research. In the quantum world this question explores (...)

On the nature of the glass transition

Colloquium — 2022-11-18T10:51:33Z

Mathieu Wyart, Ecole Polytechnique Federale de Lausanne
Wednesday, November 23, 2022 1:30 p.m. — Amphi Jaurès (E244)
Under cooling, a supercooled liquid undergoes a glass transition and stops flowing. Physicists do not agree on the microscopic reasons that make a glass solid. Some view this phenomenon as being collective in nature : it may be a signature of a thermodynamic phase transition, or being caused by kinetic constraints (where particles seek to solve a sort of Chinese puzzle).
