【报告摘要】：At heterointerfaces, due to the presence of a pronounced interplay of Coulomb and interfacial electron-phonon interactions, the systems exhibit a wide spectrum of intriguing quantum phenomena that are inaccessible in their bulk individuals, such as the emergence of interfacial superconductivity. In this talk, I will present our recent significant progresses on the studies of interfacial superconductivity at KTaO3 heterointerfaces. Remarkably, the spontaneously broken rotational symmetry will be systemically discussed in the KTaO3 heterointerface superconductors with strong spin-orbit coupling [1]. Furthermore, I will also present the intrinsic coexistence of ferromagnetism and superconductivity at the KTaO3 heterointerfaces [2], which holds promising potential applications for the realization of the topological quantum computing.
