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 […]

Marcel Franz – Quantum Matter Institute Title: d-mon: an improved transmon qubit based on a cuprate Josephson junction   Abstract: Transmon qubit, based on a superconducting Josephson junction shunted by a large capacitance, is the workhorse component powering the majority of intermediate scale quantum computers currently in operation. I this talk I will describe a […]

Lindsay LeBlanc – University of Alberta Title: Light-matter interactions in cold and ultracold neutral atomic gases: Applications to quantum memory and holonomic quantum operations Abstract: Neutral atomic gases provide fantastic opportunities for studying and controlling quantum phenomena, ranging from many-body physics to quantum computers. In our research, we use the well-known interactions between cold gases […]

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 […]

Nitin Kaushal – Quantum Matter Institute Title: Realization of magnetically frustrated Wigner crystals and a novel multiorbital model in transition metal dichalcogenide based moiré materials Abstract: Moiré materials constructed using the transition metal dichalcogenide (TMD) bilayers have been used to simulate the Hubbard model with long range Coulomb interactions procuring the lattice Wigner crystal states […]

Andrea Young – University of California Santa Barbara Title: Magnetism and superconductivity in rhombohedral graphene multilayers: triplet superconductivity, intervalley coherence, and spin orbit coupling  Abstract: The electronic band structure of rhombohedral graphene multilayers hosts van Hove singularities at which the single particle of states diverges.  I will discuss experiments in which we use electrostatic gates […]

Kaoru Yamanouchi – Institute for Attosecond Laser Facility and Department of Chemistry, University of Tokyo Title: Quantum computing of atomic and molecular problems Abstract: Two-dimensional analogs of metal-halide perovskites represent a promising platform for exciton-polariton-based technologies. They sustain strongly bound excitons that are stable at room temperature, readily enabling strong light-matter coupling at ambient conditions. In the […]
