SUMMARY:CM Seminar: Mattias Fitzpatrick – Dartmouth College: Quantum Simulation with Superconducting Circuits: Synthetic Quantum Matter to Non-Hermitian Sensing
DESCRIPTION:Mattias Fitzpatrick – Dartmouth College\nTitle: Quantum Simulation with Superconducting Circuits: Synthetic Quantum Matter to Non-Hermitian Sensing \nAbstract: In recent years\, superconducting circuits have garnered much attention due to their use in quantum computers and quantum annealers. However\, this technological platform can also be used to study problems in condensed matter and many-body physics where microwave photons are the particles of interest and interactions are engineered using superconducting qubits or other nonlinearities. In this talk\, I will describe my work building hyperbolic superconducting circuit lattices and the associated flat bands that arise in their band structure. From here\, I will discuss recent work in my new lab at Dartmouth\, where we have developed a means of controlling the effective photon hopping in lattices. Using directional amplification and phase shifters\, I will show how to create effectively tunable hopping rates in the Hermitian and non-Hermitian domains. Finally\, I will discuss nonlinearities in the gain-dominated regime and their implications for self-oscillation sensors.

SUMMARY:CM Seminar: Lesley Cohen – Chair of the Advisory Board: Non-collinear Mn3NiN Antiferromagnets
DESCRIPTION:Lesley Cohen – Chair of the Advisory Board\nTitle: Non-collinear Mn3NiN Antiferromagnets \nAbstract: 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 magnetic space group symmetry. Stimulated first by the prediction of piezomagnetism we embarked on a growth program of Mn3NiN films on various perovskite substrates by pulsed laser deposition. In this talk I will review the evidence for piezomagnetism and our observation of the anomalous Hall effect. We use scanning imaging of the anomalous Nernst effect to provide information about domain structure in our films. The phase diagram of magnetic order with biaxial strain in this family of materials predicts that compressively strained films should support a collinear ferrimagnetic phase as shown in the figure below. I will discuss the properties of this phase and implications and the magneto-optical properties crossing from the antiferromagnetic to ferrimagnetic phase. \nSpeaker Bio: Lesley Cohen is a Professor of Solid State Physics at Imperial College London. Her research focuses on quantum interference for organic thermoelectric\, energy-efficient solid-state caloric cooling\, competing for exchange antiferromagnets for spintronics and long-range triplet superconductivity. She is currently the Consul for the Faculty of Natural Sciences and Education at Imperial College and recently stepped down as head of Experimental Condensed Matter. She received the Imperial College Julia Higgins Award for her contribution to the promotion and support of women in science and remains committed to equality and diversity within STEM. \nDr. Cohen has served on numerous Boards including Superconductivity\, Science and Technology; Imperial College Consultants ICON; the Education Board for the Institute of Physics; Kings College London Science Advisory Board; and the External Advisory Board of IFW Dresden and the EPSRC Materials Strategic Advisory Technical Panel.

SUMMARY:CM Seminar: Ting Ge – University of South Carolina: Mechanics of Non-Concatenated Ring Polymers – Effects of Topology Revealed by Molecular Simulations
DESCRIPTION:Ting Ge – University of South Carolina\nTitle: Mechanics of Non-Concatenated Ring Polymers – Effects of Topology Revealed by Molecular Simulations \nAbstract: 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 non-concatenated ring polymers with distinctive topology. While many aspects of the statics and dynamics of ring polymers have been elucidated in the past several decades\, the structure-property relationship has not been completely established for ring polymer mechanics. Using molecular simulations with perfect control of polymer topology\, we make elastomers and thermoplastics out of non-concatenated ring polymers and investigate their mechanical properties during large deformation and failure. The simulations reveal that the elastomers made of cross-linked ring polymers are significantly more stretchable than cross-linked linear polymers [1]. Compared to linear polymers\, the entanglements between ring polymers do not act as effective cross-links. As a result\, the stretchability of cross-linked ring polymers is determined by the maximum extension of polymer strands between cross-links rather than between trapped entanglements as in cross-linked linear polymers. The simulations also reveal that the thermoplastics made of ring polymers fail through crazing as their linear counterparts under tensile loading [2]. The stable craze formation indicates the existence of an entanglement network in glassy ring polymers. Nevertheless\, the entanglement network consists of only a fraction of the topological constraints that determine the conformations of ring polymers. Both the structural features of the ring polymer craze and the drawing stress during the craze formation are related to the underlying entanglement network. Besides the simulations\, molecular theories have been developed to delineate the mechanical behaviors of ring elastomers and ring thermoplastics. The studies demonstrate the use of ring polymers as a transformative pathway to tailor polymer mechanics\, propelling a new paradigm of topological polymer physics entering materials science. \n[1] “Superstretchable elastomer from cross-linked ring polymers”\, J.
