SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Discovering emergent correlated states and quantum phase transitions in a moiré superlattice\n\n\nBy Wei Yang\nInstitute of Physics\, Chinese Academy of Sciences\, Beijing 100190\, China\nNew 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 superlattice\, it leads to moiré flat band where various correlated states are developed. In this talk\, I will focus on the twisted double bilayer graphene\, and talk about the field-tunable exotic phases such as isospin polarized correlated insulators\, anomalous quantum oscillations (QOs) of insulating states\, and first-order quantum phase transitions where interplays among correlation\, isospin polarization\, and Landau quantization are important.\n\nBiography\nDr. Wei Yang received his Ph.D in condensed matter physics from Institute of Physics\, Chinese Academy of Sciences in 2014. He worked as a postdoc from 2014 to 2019\, first at École Normale Supérieure and CNRS in Paris\, and then at ICOF-The Institute of Photonic Sciences in Barcelona. Then\, he joined Institute of Physics CAS as a faculty member since 2019. His research interest lies in exploring the novel phenomena emerging from low dimensional system including carbon nanotube\, graphene and moiré superlattices\, by quantum transport\, high frequency noise thermometry\, and nano-mechanics.\n\n\n\nWhere ?\nESPCI\, Room Boreau\, building C\, 2nd floor\nZoom link: https://espci.zoom.us/j/89301826401?pwd=cnkvMjh6K0Z4YldFcnMvREovWUQ3QT09\nID: 893 0182 6401\nPasscode: Pythagoras\nContact/to subscribe or unsubscribe: seminaires-lpem@espci.fr

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Supershear cracks in Tensile Fracture : How fast can materials break ?\nMeng Wang\, Hebrew University \nWhere : ESPCI\, Charpak room \nBrittle 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 energy flux with dissipation. Using energy balance\, fracture mechanics perfectly describes crack motions ; accelerating from nucleation to their maximal speed of CR\, the Rayleigh wave speed. Beyond CR\, tensile fracture is generally considered to be impossible [1]\, [2].\nRecently\, the potential emergence of an entirely new branch of fracture that is not incorporated in classical fracture mechanics has been predicted in lattice models to occur at high applied stretch [3]\, [4]. This theory predicts tensile cracks that are able to exceed the shear wave velocity\, CS\, and potentially even the dilatation waves speed\, CP [5]. Here\, by the use of brittle hydrogels\, we experimentally demonstrate that such a wholly new and different class of tensile cracks indeed exists. We demonstrate that their dynamics are not governed by the principle of energy balance\, the cornerstone of the classical theory of fracture. This new branch of cracks smoothly surpasses CS to reach unprecedented speeds that approach the speed of dilatation waves. The transition from `classical’ cracks to these `supershear’ cracks takes place at critical values of applied strains. We\, furthermore\, show that the values of these\, rather moderate (18-20%)\, critical strains are intimately related to the microscopic material structure. While it is still unclear whether this intriguing fracture mode is indeed that predicted theoretically by Marder [3]\, it is clear that these extreme tensile cracks have never before been clearly observed in experiments. This new mode of tensile fracture represents a fundamental paradigm shift in our understanding of ‘how things break’. \n[1] L. B. Freund\, Dynamic fracture mechanics.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Extending the laws of thermodynamics for arbitrary autonomous quantum systems\n  \nBy Cyril Elouard\, Laboratoire de Physique et Chimie Théorique\, Université de Lorraine \nWhere : ESPCI\, Room Charpak\, entrance building\, \nQuicklink: https://espci.zoom.us/j/88089230296?pwd=oay4biTOEsi75HbcfiF6reRHGTzGbf.1\nID: 880 8923 0296\nPasscode: JCMaxwell\nContact/to subscribe or unsubscribe: seminaires-lpem@espci.fr \n  \nUnderstanding quantum setups with the concepts of nonequilibrium thermodynamics has attracted a lot of attention over the last decades. The emerging field of Quantum Thermodynamics is motivated by the recent ability to manipulate elementary open quantum systems to realize quantum engine cycles. Its core concepts build on the advances in nonequilibrium thermodynamics developed in the 90s to describe molecular engines\, which managed to expressed fundamental constraints on the energy flows valid far from equilibrium and from the thermodynamic limit. \nBy analyzing engines based on quantum systems\, it was possible to show first occurrences of quantum advantages in motor and refrigerator performances exploiting properties specific to the quantum world such as coherent superpositions\, entanglement\, indistinguishable particles… Other quantum phenomena such as the backaction of a quantum measurement have been revealed as new sources of irreversibility\, but also new resources able to fuel engines. \nMore generally\, a goal of the community is to express the fundamental constraints on energy flows valid at the quantum scale — that is the quantum version of the laws of nonequilibrium thermodynamics — to understand the limitations on such engines and optimize their performances\, but also to find new tools to characterize complex quantum systems. While consistent frameworks have been proposed to to so for quantum open systems coupled to classical work and heat sources\, it is desirable to understand energy exchange between quantum systems. This is in particular necessary to address quantum batteries or nanoscale autonomous machines which hold the promises of interesting advantages. \nIn this seminar\, I will present a formalism we recently introduced to address this situation. We show that any quantum system can be understood as a hybrid source of heat and work\, the former being constrained by a quantum version of the Second law of thermodynamics involving an apparent temperature related to its Von Neuman entropy. Ideal cases of pure work and heat sources can be retrieved\, while the formalism also allows us to analyze situations far from classical thermodynamics\, such elementary engines based only on small quantum systems as heat and work sources. Our formalism provides a basis to analyze and optimize energy transfers occurring in quantum systems\, valid at any scale and any coupling intensity.
