Long-range propagation of ocean swell

William Young (University of California at San Diego) — June 26, 2018 Abstract : The propagation of ocean surface waves is a happy example in which a linear theory (almost) explains ocean observations. I’ll review the history of this problem, (...) | ↦ Lire la suite

Fast Magnetic Reconnection in Space and Astrophysical Plasmas

Amitava Bhattacharjee (Princeton University) — June 12, 2018 Abstract : Magnetic reconnection is the process by which the enormous energy stored in magnetic fields can be released as the kinetic energy of charged particles. A principal (...) | ↦ Lire la suite

Towards a renormalization group for networks of neurons

William Bialek (Princeton University) — May 29, 2018 Abstract : In many systems we can describe emergent macroscopic behaviors, quantitatively, using models that are much simpler than the underlying microscopic interactions ; we understand the (...) | ↦ Lire la suite

Nanopores in 2D Materials

Aleksandra Radenovic (École Polytechnique Fédérale de Lausanne) — May 15, 2018 Abstract : In this talk I will address novel applications ranging from identification of single nucleotides, but as well go beyond DNA sequencing and provide effective (...) | ↦ Lire la suite

The direct observation of gravitational waves

Bruce Allen (Max Planck Institute for Gravitational Physics, Hannover & University of Wisconsin-Milwaukee) — March 6, 2018 Abstract : For the first time, starting more than two years ago, the advanced LIGO and Virgo instruments have (...) | ↦ Lire la suite

Fluids of light in semiconductor lattices

Jacqueline Bloch (Center for Nanoscience and Nanotechnology, Marcoussis)— February 6, 2018 Abstract : When confining photons in semiconductor lattices, their physical properties can be deeply modified. Photons can behave as massive, or even (...) | ↦ Lire la suite

Stories of grains in fluids :

from impact in dense suspensions to micro-avalanches in plant cells

Yoël Forterre — January 23, 2018 Abstract : Over the past twenty years, great progress has been made in our understanding of how granular matter flows, a topic of both basic and practical interest. A distinctive feature of granular flows is that (...) | ↦ Lire la suite

Can we save energy, jobs, and growth at the same time ?

Jean-Marc Jancovici — January 9, 2018 Abstract : The depletion of natural resources, with oil to start with, and the need for a stable climate, will make it harder and harder to pursue economic growth as we know it. It has now become urgent to (...) | ↦ Lire la suite

Tests of quantum mechanics and gravitation with atom interferometry

Mark Kasevich (Stanford University) — December 12, 2017 Abstract : Recent de Broglie wave interference experiments with atoms have achieved wavepacket separations as large as 54 cm over time intervals of 2 sec [1, 2]. These experiments, and (...) | ↦ Lire la suite

Extreme events in nature, rogue wave in optics

John Dudley (Université de Franche Comté) — November 28, 2017 Abstract : Understanding extreme events in nature is intrinsically challenging because the events themselves are rare, and often appear in environments where measurements are (...) | ↦ Lire la suite
