Lesley Cohen – Chair of the Advisory Board Title: Non-collinear Mn3NiN Antiferromagnets Abstract: Antiferromagnets (AFM) hold interest because of their potential for application in high density, high speed spintronic devices, as  an active layer and also as a component in superconducting S/AFM/S Josephson Junctions. Frustrated non-collinear antiferromagnets offer additional attractive functional properties due to their […]

Ting Ge – University of South Carolina Title: Mechanics of Non-Concatenated Ring Polymers – Effects of Topology Revealed by Molecular Simulations Abstract: Few aspects are as prevalent and important as topology in polymer mechanics, which provides an essential foundation for versatile functions of polymeric materials. Recent advances in chemistry have enabled the precise synthesis of […]

Lea Nienhaus – Florida State University Title: Stressing Halide Perovskites: Nanoscale Investigation of the Properties of Perovskite Thin Films Abstract: Solution-processed perovskite thin films consist of small grains with a size of 20 - 2000 nm connected by grain boundaries. As a result, there is a vast inhomogeneity in the optical and electronic properties of […]

Joe Checkelsky– Massachusetts Institute of Technology Title: Natural Superlattice Design of Modulated Superconductors Abstract: Connecting theoretical models for exotic quantum states to real materials is a key goal in quantum materials synthesis.  Two-dimensional model systems have been proposed to host a wide variety of exotic phases- historically a number of techniques have been used to […]

Xiaodong Xu – University of Washington Title: Observation of Fractional Quantum Anomalous Hall Effect Abstract: The interplay between spontaneous symmetry breaking and topology can result in exotic quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state, which exhibits an integer quantum Hall effect at zero magnetic field due to topologically […]

Jeff Sonier – Simon Fraser University Title: Muon Studies of Superconducting UTe2 Abstract: Recently discovered UTe2 is believed to be a long-sought spin-triplet superconductor, but its magnetic properties and superconducting order parameter are matters of controversy. The observation of a nonzero polar Kerr effect in the superconducting state of UTe2 single crystals exhibiting two phase […]
