SUMMARY:Chunli Huang : Microscopic Origin of Orbital Magnetization in Chiral Superconductors and Intervalley Coherent States
DESCRIPTION:\nChunli Huang, University of Kentucky\n\n\n\nLe résumé :\n\n\n\nRecent experiments in rhombohedral multilayer graphene have shown that this seemingly simple collection of carbon atoms can host a remarkable variety of electronic phases that previously appeared only across many different materials. These include spin and orbital ferromagnetism, electronic crystals phases, and both spin-singlet and spin-triplet superconductivity.\n\n\n\nMore recently, entirely new states have been realized, including intervalley coherent states, fractional Chern insulators and chiral superconductors. The chiral superconductor has many unusual magnetic properties, such as field-induced chirality reversal, setting it apart from all previously known superconductors.\n\n\n\nI will first describe a transport signature of intervalley coherence, in which a static magnetic field induces GHz oscillations of the orbital magnetization. I will then present a microscopic theory of orbital magnetization in chiral superconductors, highlighting the key theoretical steps that close a longstanding gap in computing orbital magnetization in superconductors. \n\n\n\nContact: andrej.meszaros@universite-paris-saclay.fr ( mailto:andrej.meszaros@universite-paris-saclay.fr )\n
