A Skyrme Model with Novel Chiral Symmetry Breaking (2023)
Journal Article
Sutcliffe, P. (2023). A Skyrme Model with Novel Chiral Symmetry Breaking. Symmetry, integrability and geometry: methods and applications, 19, Article 051. https://doi.org/10.3842/sigma.2023.051

An extension of the Skyrme model is presented in which derivative terms are added that break chiral symmetry to isospin symmetry. The theory contains just one new parameter and it reduces to the standard Skyrme model when this symmetry breaking param... Read More about A Skyrme Model with Novel Chiral Symmetry Breaking.

High-Dimensional Time Series Segmentation via Factor-Adjusted Vector Autoregressive Modeling (2023)
Journal Article
Cho, H., Maeng, H., Eckley, I. A., & Fearnhead, P. (2023). High-Dimensional Time Series Segmentation via Factor-Adjusted Vector Autoregressive Modeling. Journal of the American Statistical Association, https://doi.org/10.1080/01621459.2023.2240054

Vector autoregressive (VAR) models are popularly adopted for modeling high-dimensional time series, and their piecewise extensions allow for structural changes in the data. In VAR modeling, the number of parameters grow quadratically with the dimensi... Read More about High-Dimensional Time Series Segmentation via Factor-Adjusted Vector Autoregressive Modeling.

Wild Local Structures of Automorphic Lie Algebras (2023)
Journal Article
Duffield, D. D., Knibbeler, V., & Lombardo, S. (2024). Wild Local Structures of Automorphic Lie Algebras. Algebras and Representation Theory, 27(1), 305-331. https://doi.org/10.1007/s10468-023-10208-y

We study automorphic Lie algebras using a family of evaluation maps parametrised by the representations of the associative algebra of functions. This provides a descending chain of ideals for the automorphic Lie algebra which is used to prove that it... Read More about Wild Local Structures of Automorphic Lie Algebras.

Bootstrapping Witten diagrams via differential representation in Mellin space (2023)
Journal Article
Li, Y., & Mei, J. (2023). Bootstrapping Witten diagrams via differential representation in Mellin space. Journal of High Energy Physics, 2023(7), Article 156. https://doi.org/10.1007/jhep07%282023%29156

We explore the use of the differential representation of AdS amplitudes to compute Witten diagrams. The differential representation expresses AdS amplitudes in terms of conformal generators acting on contact Witten diagrams, which allows us to constr...

Spatial Dynamics with Heterogeneity (2023)
Journal Article
Patterson, D. D., Staver, A. C., Levin, S. A., & Touboul, J. D. (online). Spatial Dynamics with Heterogeneity. SIAM Journal on Applied Mathematics, 84(3), S225-S248. https://doi.org/10.1137/22m1509850

Spatial systems with heterogeneities are ubiquitous in nature, from precipitation, temperature, and soil gradients controlling vegetation growth to morphogen gradients controlling gene expression in embryos. Such systems, generally described by nonli... Read More about Spatial Dynamics with Heterogeneity.

A Sequential Cross-Sectional Analysis Producing Robust Weekly COVID-19 Rates for South East Asian Countries (2023)
Journal Article
Almohaimeed, A., & Einbeck, J. (2023). A Sequential Cross-Sectional Analysis Producing Robust Weekly COVID-19 Rates for South East Asian Countries. Viruses, 15(7), Article 1572. https://doi.org/10.3390/v15071572

The COVID-19 pandemic has expanded fast over the world, affecting millions of people and generating serious health, social, and economic consequences. All South East Asian countries have experienced the pandemic, with various degrees of intensity and...

Comments on Non-invertible Symmetries in Argyres-Douglas Theories (2023)
Journal Article
Carta, F., Giacomelli, S., Mekareeya, N., & Mininno, A. (2023). Comments on Non-invertible Symmetries in Argyres-Douglas Theories. Journal of High Energy Physics, 2023(7), Article 135. https://doi.org/10.1007/jhep07%282023%29135

We demonstrate the presence of non-invertible symmetries in an infinite family of superconformal Argyres-Douglas theories. This class of theories arises from diagonal gauging of the flavor symmetry of a collection of multiple copies of Dp(SU(N)) theo...
