[Quantum Matter Joint seminar: Quantum Matter in Mathematics and Physics & Topological Quantum Matter, Dec 8 Friday 2:30 - 4 pm] Let us welcome Da-Chuan! -------------------- This seminar will be in person! Time: Dec 8 Friday 2:30 - 4 pm ET Location: Harvard CMSA G10 Zoom: https://harvard.zoom.us/j/977347126 Password: cmsa —————————————————— Da-Chuan Lu (UCSD) Title: Fermi surface symmetric mass generation and its application in nickelate superconductor Abstract: Symmetric mass generation (SMG) is a novel interaction-driven mechanism that generates fermion mass without breaking symmetry, unlike the standard Anderson-Higgs mechanism. SMG can occur in the fermion system without quantum anomalies. In this talk, I will focus on the SMG for the systems with finite fermion density, i.e., the Fermi surface. I will discuss the Fermi surface anomaly and Fermi surface SMG. Lastly, I will talk about its application in the newly found nickelate superconductors, where the superconductivity emerges without a nearby spontaneous symmetry-breaking phase. -------------------- Subscribe to Harvard CMSA Quantum Matter and other seminar videos (more to be uploaded): https://www.youtube.com/playlist?list=PL0NRmB0fnLJQAnYwkpt9PN2PBKx4rvdup Subscribe to Harvard CMSA seminar mailing list: https://forms.gle/1ewa7KeP6BxBuBeRA --- Harvard University CMSA, 20 Garden Street, Cambridge, MA 02138 https://cmsa.fas.harvard.edu
