学术报告（2025年11月3日15:00）：Superfluid density wave in two weakly linked superconducting ultrathin films

主 持 人：叶鹏教授

报告摘要：A sufficiently strong parallel magnetic field between two weakly coupled superconducting ultrathin films produces staggered supercurrent loops and a superfluid density wave, yielding an inhomogeneous Fulde-Ferrell Larkin-Ovchinnikov (FFLO) state characterized by Josephson vortex-antivortex pairs. Conversely, a weak parallel magnetic field produces a uniform Fulde-Ferrell (FF) state. The transition between these states falls into the universality class of 2D commensurate-incommensurate transitions.
