Evidence for p-wave pairing and hybridizing Majoranas in artificial finite-size Shiba chains By Jens Wiebe Department of Physics, Universität Hamburg, Germany   A magnetic chain on an s-wave superconductor hosting a spin spiral or strong spin-orbit coupling can potentially realize a one-dimensional topological superconductor with Majorana bound states on its edges.  Here, we investigate artificial…

How amorphous materials yield under stress : a new kind of out of equilibrium phase transition Giulio Biroli (ENS) I will show that a new kind of out of equilibrium phase transition is at the core of how amorphous solids yield in response to external deformations—a phenomenon that is crucial both for practical applications and…

On Monday 28th June at 11:30, Pedro Reis and his team will guide you virtually through the fleXLab at EPFL and will discuss the mechanics of rods and knots. It used to be that academic seminars involved a researcher visiting a host institution to deliver a talk and meet with colleagues (do you remember those…

Ions in motion : Effect of Oscillatory Electric Fields   Carlos Drummond Centre de Recherche Paul Pascal (CRPP), UPR 8641-CNRS, Université de Bordeaux, Pessac F-33600, France Zoom link : https://espci.zoom.us/j/85635514099?pwd=dHhMVHQxbENRVkc0amxCelg5cEN2Zz09 ID de réunion : 856 3551 4099 Code secret : 102958   Abstract: The dynamic response to applied electrical potentials is a topic of fundamental…

Tuning Properties and Functionality in the Modulated Self-Assembly of Metal-Organic Frameworks Prof. Ross S. Forgan WestCHEM School of Chemistry, University of Glasgow Online on Zoom https://us02web.zoom.us/j/84312479733?pwd=ZUhSUVh1WFBnQVhRQnJTZmIvVnVzUT09 Meeting ID: 843 1247 9733 Secret code: K3nwq9 Metal-organic frameworks (MOFs) are network materials comprised of organic ligands connected by metal ion clusters into multidimensional structures that often have…

Plasma flow reactor for functionalization of small organic molecule A presentation from Stéphanie Ognier (Chimie ParisTech - PSL)     Plasma is a powerful technology for the generation of reactive species without any catalyst. It is currently used for the modification of materials in several areas of industry but underused in the field of small molecules…

Nanoscale Turing patterns in bismuth monolayer   Yuki Fuseya  University of Electro-Communications, Tokyo   Ordered patterns can arise out of randomness during morphogenesis. An explanation for this puzzle was put forward by Turing, who explained the emergence of stational patterns by invoking the interplay between an activator and an inhibitor with different diffusion rates .…

Teaching an old foam new tricks: material design, memories and learning in aging solids Daniel Hexner Disordered solids are often out of equilibrium, evolving slowly as they age. The small incremental changes inherent in the aging process reduce the internal stresses through microscopic plastic deformations within the material. While often considered as merely a nuisance…
