Having a broad view of the main current research topics is difficult but crucial to choose
the internship and PhD subjects, and more generally the research directions in physics.
During the first semester, a series of seminars “Physics Now” will allow the M2 ICFP students
to broad their knowledge on the current hot topics in physics and get information on
research groups and themes in France and abroad.

Seminars are organised for each program; students of one program are welcome to attend
the seminars of another if the schedule permits.

Schedule of the Seminars

 “Soft matter Now”

Tuesday 13th September at 01:00pm – Conf IV
Speaker: Florence Elias
Title: Liquid Foams for Environmental Physics

Tuesday 04th october at 01:30pm – Conf IV
Speaker: Sebastian Wolf

 “Theoretical Physics Now”

Tuesday 11th october – L367
Speaker: Raffaele-Tito D’Agnolo
Title: Voyages Beyond the Standard Model

Abstract: I will give a modern perspective on some of the key questions in particle physics, ranging from the size of the Universe to the value of the Higgs boson mass and the microscopic nature of dark matter. I will discuss the current status of our most appealing explanations for these mysteries and what are our best shots at a discovery in the next decade. In this exploration, theory and experiment go hand in hand. Without a deep theory understanding we are lost in a humongous parameter space that is impossible to explore within our lifetimes. Without experiment we are lost in sterile speculations about principles that are not guaranteed to be realized in Nature.

Tuesday 22th november – L367
Speaker: Julien Larena
Title: Cosmology: open problems and new observables

Abstract: The cosmological standard model, thanks to its remarkable precision, allows one to formulate important questions about the origin of the Universe, its evolution and its large-scale structure. In the first part of this talk, I will summarise the current status of this standard model, highlighting open problems and current research trends in the community to address them In the second part, taking as an example recent advances I have contributed to in the field of gravitational lensing, I will try to illustrate how theoretical considerations about the accuracy of the cosmological model can lead to the design and implementation of new observables, opening new ways to try and answer some of the open problems.

Tuesday 29th november

Speaker: Freddy Bouchet
Title: Statistical physics approaches for climate dynamics

Abstract: I will discuss a set of recent developments in non-equilibrium statistical physics applied to climate, and the global state of the art on this subject. The first application will be extreme heat waves as an example of rare events with huge impacts. The second one will be the study of rare trajectories that suddenly drive a turbulent flow from one attractor to a completely different one, related to abrupt climate changes on Jupiter or the Earth troposphere. To understand these phenomena, we have developed new tools inspired by statistical physics approaches in condensed matter and other fields. We use theoretical approaches on one hand: path integrals and large deviation theory; and numerical ones on the other hand: rare event simulations analogous to diffusion Monte-Carlo algorithms and machine learning.

Tuesday December 06th– L367
Speaker: Nikita Kavokine
Title: Quantum plumbing: the mysteries of nanoscale flows
Abstract: Liquids are usually described within classical physics, whereas solids require the tools of quantum mechanics. I will show how in nanoscale systems this distinction no longer holds. At these scales, liquid flows may in fact exhibit quantum effects as they interact with electrons in the solid walls. I will first discuss the quantum friction phenomenon, where charge fluctuations in the liquid interact with electronic excitations in the solid to produce a hydrodynamic friction force. Using many-body quantum theory, we predict that this effect is particularly important for water flowing on carbon-based materials, and we obtain experimental evidence of the underlying mechanism from pump-probe terahertz spectroscopy. I will then show how the theory can be pushed one step further to describe hydrodynamic Coulomb drag – the generation of electric current by a liquid in the solid along which it flows. This phenomenon involves a subtle interplay of electrostatic and electron-phonon interactions, and suggests strategies for designing materials
