Identifiability and numerical algebraic geometry
PLoS ONE, 2019 A common problem when analyzing models, such as mathematical modeling of a biological process, is to determine if the unknown parameters of the model can be determined from given input-output data.

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal
Advanced Materials, EarlyView.Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Singular solutions in soft limits
Journal of High Energy Physics, 2020 A generalization of the scattering equations on X (2, n), the configuration space of n points on ℂℙ1, to higher dimensional projective spaces was recently introduced by Early, Guevara, Mizera, and one of the authors.

Manipulating Individual Topological Solitons and Bisolitons in an Electronic System
Advanced Materials, EarlyView.While localized topological modes in quantum materials promise loss‐less delivery of classical and quantum information, manipulating them individually has been challenging. This work succeeded in manipulating topological solitons formed along atomic wires on silicon surfaces with high reproducibility in various ways, including translating, transforming

Towards analytic structure of Feynman parameter integrals with rational curves
Journal of High Energy Physics, 2022 We propose a strategy to study the analytic structure of Feynman parameter integrals where singularities of the integrand consist of rational irreducible components.

Advanced Photonics Research, EarlyView.Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...

Generalized planar Feynman diagrams: collections
Journal of High Energy Physics, 2020 Tree-level Feynman diagrams in a cubic scalar theory can be given a metric such that each edge has a length. The space of metric trees is made out of orthants joined where a tree degenerates.

Tropical Grassmannians, cluster algebras and scattering amplitudes
Journal of High Energy Physics, 2020 We provide a cluster-algebraic approach to the computation of the recently introduced generalised biadjoint scalar amplitudes related to Grassmannians Gr(k, n). A finite cluster algebra provides a natural triangulation for the tropical Grassmannian whose

Techniques and Advances in Ultrafast Photography
Advanced Photonics Research, EarlyView.This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
