SUMMARY:Speaker: Sinead Griffin ( LBL)- Title: Party like it's LK99?
DESCRIPTION:Research Progress Meeting \nDate: August 15\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Sinead Griffin (LBL) \nTitle: Party like it’s LK99?\n \nAbstract: A recent report of room temperature superconductivity at ambient pressure in Cu-substituted apatite (`LK99′) has invigorated interest in the understanding of what systems and mechanisms allow for high-temperature superconductivity. In this talk\, I will describe my recent work on identifying the origins of correlated isolated flat bands at the Fermi level in lk99\, a common signature of high transition temperatures in already-established families of superconductors. I elucidate the origins of these isolated bands as arising from a structural distortion induced by the Cu ions and a chiral charge density wave from the Pb lone pairs. These results suggest that a minimal two-band model can encompass much of the low-energy physics in this system. Finally\, I discuss the implications of my results on possible superconductivity in Cu-doped apatite. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037
