SUMMARY:Workshop / Seminar:CM-AMO Seminar | Scanning time-resolved optical studies on Kagome superconductors
DESCRIPTION:The kagome lattice provides a fascinating playground to study geometrical frustration\, topology and strong correlations. The newly discovered kagome metals AV_3Sb_5 (A = K\, Rb\, Cs) exhibit exotic phases including charge density waves (CDWs) and superconductivity. In our study\, we perform scanning birefringence and circular dichroism (CD) microscopy on CsV_3Sb_5. The scanning birefrigence demonsate six-fold rotational symmetry breaking in the CDW phase and three domains that are 120 degree to each other. The emergence of opposite CD domains within the same birefringence domain\, along with field-induced CD switching\, indicate broken time-reversal symmetry. Furthermore\, ultrafast pump-probe reflectivity measurements reveal a splitting of charge density wave induced phonon modes in all three birefringence domains. Such a breaking in degeneracy corroborates the six-fold rotation symmetry breaking in the charge ordered phase. I will also discuss the CDW fluctuations from the pump-probe measurement.\n\nReferences\n\n[1] Y. Xu\, Z. Ni\, Y. Liu\, B. Ortiz\, Q. Deng\, S. Wilson\, B. Yan\, L.

SUMMARY:Workshop / Seminar:Probing Electrochemical Reactivity Under Nanoconfinement in Layered Electrode Materials
DESCRIPTION:Electrochemical processes are vital for global decarbonization efforts because they are central to many energy-efficient storage and conversion technologies and can also be leveraged for large scale chemical manufacturing. In the context of these energy applications\, it is necessary to understand factors that control the kinetics and selectivity of electrochemical reactions. At the electrode level\, many factors\, including the chemical composition\, atomic or molecular structure\, surface area\, and morphology\, have been leveraged to direct electrochemical reactions. An emerging strategy is to geometrically confine the electrochemical reaction within a porous electrode material. This places a physical boundary around the electrochemical reaction and thus defines the reaction microenvironment\, while also spatially restricting the reactants and products. Experimental studies of nanoconfinement effects on electrochemical reactions require electrochemical interfaces with well-defined environments. In this presentation\, I will discuss our materials chemistry approach to define the confined electrochemical environment within molecularly pillared transition metal oxides\, and our study of electrochemical reactions taking place within these electrodes using in situ and operando electrochemical methods.

SUMMARY:Meeting:Psycholinguistics
DESCRIPTION:The psycholinguistics discussion group is a meeting of several lab groups from Linguistics\, Psychology\, and other departments that all share common interests in language processing\, including comprehension\, production\, and acquisition. The discussion group is an informal venue for presenting research findings\, for developing new ideas\, and for connecting with the many language scientists across the University who are interested in the psychology and neuroscience of human language.
