The study of vortex matter can help better understand the macro properties and the superconducting mechanism of superconductors. Moreover, vortex matter provides an important platform for the study of many-body interactions and can be used to design quantum devices. Our group mainly focuses on the study of vortex manipulations in various superconducting films and single crystals. The research interests include: nanostructured superconductor, vortex lattice/dynamics and artificial spin ice.
