The broad range of physical effects at the intersection of superconductivity and magnetism in bulk crystals, thin films, and artificial 2D hybrid heterostructures constitutes a rich platform to explore, discover, and control new behaviors. The boundaries between superconductivity and magnetism are fluid, with thematically interconnected phenomena in magnetic superconductors, vortex matter, topological superconductors and superconducting/ferromagnetic hybrid heterostructures.
The program develops the basic science in support of the current DOE Office of Basic Energy Sciences (BES) objectives related to quantum materials and microelectronics. Recent research has focused on exploring (i) the non-trivial Fermi surface topology of novel Kagome lattice superconductors, such as CsV3Sb5, (ii) developing a phenomenological theory to elucidate the magnetic helical state of the high-temperature magnetic superconductors, such as RbEuFe4As4, (iii) extending Kohler’s rule of magnetoresistance to account for novel transport behavior in various topological systems, and (iv) demonstrating the coherent coupling of two magnonic resonators with a superconducting circuit.
Following storied research of nearly four decades devoted to DOE-BES programs on Experimental Condensed Matter Physics with numerous notable discoveries, this program will be closed in 2023.
