"Stumbled upon this by accident today. Was utterly blown away to discover that Norman Rockwell, the King of Kitsch, was capable of creating a work this powerful and politically engaged. The painting, titled "Southern Justice (Murder in Mississippi)," depicts the 1965 murder of the three civil rights workers Chaney, Goodman, and Schwerner. Note how the killers appear only as shadows." - Stephen D. O'Leary

Gatemonium: A Voltage-Tunable Fluxonium
We present a new fluxonium qubit design, gatemonium, based on an all superconductor-semiconductor hybrid platform exhibiting gate voltage tunability of $E_J$. We first show the principle of fluxonium operation in epitaxial Al/InAs heterostructure where the single Josephson junction can be controlled using gate voltage control, effectively tuning the ``weight'' of the fictitious phase particle. The spectroscopy of the qubit shows tunability between plasmons to fluxons and their hybrid spectrum. …

Abstract: Minimal submanifolds constitute a central area within the realm of differential geometry, due to their many applications in various branches of physics. In this thesis we will employ a recent result of S. Gudmundsson and T.J. Munn to construct minimal submanifolds of the classical compact Riemannian symmetric spaces using eigenfunctions.

Mild-to-wild plasticity of Earth's upper mantle
The flow of Earth's upper mantle has long been considered to occur by slow and near-continuous creep. Such behaviour is observed in classical high-temperature deformation experiments and is a fundamental component of geodynamic models. However, the latest generation of high-resolution experiments, capable of sensing temporal heterogeneities in rates of dislocation motion, have revealed that materials ranging from metals to ice exhibit a spectrum of behaviours termed mild-to-wild plasticity. It …

Transient and steady-state dislocation creep of olivine controlled by dislocation interactions at the isostress endmember
The rheological behaviour of olivine deforming by dislocation creep controls geodynamic processes that involve steady-state flow or transient viscosity evolution. Longstanding rheological models applied to both contexts assume that dislocation creep of olivine aggregates occurs close to the isostrain endmember with each grain deforming to the same strain but supporting different stress. Here, we test this assumption by constructing isostrain and isostress models based on flow laws for single cr…
