Discovering emergent correlated states and quantum phase transitions in a moiré superlattice By Wei Yang Institute of Physics, Chinese Academy of Sciences, Beijing 100190, China New phase of matter usually emerges when a given symmetry breaks spontaneously, which can involve charge, spin, and valley degree of freedoms. By twisting graphene multilayer to form a moiré…

Supershear cracks in Tensile Fracture : How fast can materials break ? Meng Wang, Hebrew University Where : ESPCI, Charpak room Brittle materials fail by means of rapid cracks. At their tips, tensile cracks dissipate elastic energy stored in the surrounding material to create newly fractured surfaces, precisely maintaining `energy balance' by exactly equating the…

Quantum Matter Explored by Light Experiments   By Johan Chang, Physik-Institut,Universität Zürich, Winterthurerstrasse 190, CH-8057 Zürich, Switzerland Where : ESPCI, Room Boreau, building C, 2nd floor Superconductivity, representing a macroscopy quantum state, is perhaps the best example of quantum matter. In this talk, I will present recent synchrotron experiments on tuneable quantum matter problems. Especially…
