Bethe phase including proton excitations (2020)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2020). Bethe phase including proton excitations. Physical Review D, 101(1), Article 016018. https://doi.org/10.1103/physrevd.101.016018

We evaluate the contribution of inelastic intermediate states (such as p → N excitations) to the phase between the one-photon-exchange and the “nuclear” high energy pp scattering amplitudes as t → 0, caused by multiphoton diagrams. It turns out to be... Read More about Bethe phase including proton excitations.

Nonparametric predictive inference for comparison of two diagnostic tests (2020)
Journal Article
Alabdulhadi, M., Coolen-Maturi, T., & Coolen, F. (2021). Nonparametric predictive inference for comparison of two diagnostic tests. Communications in Statistics - Theory and Methods, 50(19), 4470-4486. https://doi.org/10.1080/03610926.2020.1719157

An important aim in diagnostic medical research is comparison of the accuracy of two diagnostic tests. In this paper, comparison of two diagnostic tests is presented using nonparametric predictive inference (NPI) for future order statistics. The test...

Bosonic Symmetries of $(2,0)$ DLCQ Field Theories (2020)
Journal Article
Lambert, N., Lipstein, A., Mouland, R., & Richmond, P. (2020). Bosonic Symmetries of $(2,0)$ DLCQ Field Theories. Journal of High Energy Physics, 2020(01), Article 166. https://doi.org/10.1007/jhep01%282020%29166

We investigate symmetries of the six-dimensional (2,0) theory reduced along a compact null direction. The action for this theory was deduced by considering M-theory on AdS7×S4 and reducing the AdS7 factor along a time-like Hopf fibration which breaks...

Electron Compton scattering and the measurement of electron momentum distributions in solids (2020)
Journal Article
Talmantaite, A., Hunt, M., & Mendis, B. (2020). Electron Compton scattering and the measurement of electron momentum distributions in solids. Journal of Microscopy, 279(3), 185-188. https://doi.org/10.1111/jmi.12854

Electron Compton scattering is a technique that gives information on the electron momentum density of states and is used to characterize the ground state electronic structure in solids. Extracting the momentum density of states requires us to assume... Read More about Electron Compton scattering and the measurement of electron momentum distributions in solids.

Nonlocal gravity with worldline inversion symmetry (2020)
Journal Article
Abel, S., Buoninfante, L., & Mazumdar, A. (2020). Nonlocal gravity with worldline inversion symmetry. Journal of High Energy Physics, 2020(1), Article 3. https://doi.org/10.1007/jhep01%282020%29003

We construct a quadratic curvature theory of gravity whose graviton propagator around the Minkowski background respects wordline inversion symmetry, the particle approximation to modular invariance in string theory. This symmetry automatically yields... Read More about Nonlocal gravity with worldline inversion symmetry.

Scattering of compact oscillons (2020)
Journal Article
Hahne, F., Klimas, P., Streibel, J., & Zakrzewski, W. (2020). Scattering of compact oscillons. Journal of High Energy Physics, 2020(1), Article 6. https://doi.org/10.1007/jhep01%282020%29006

We study various aspects of the scattering of generalized compact oscillons in the signum-Gordon model in (1+1) dimensions. Using covariance of the model we construct traveling oscillons and study their interactions and the dependence of these intera... Read More about Scattering of compact oscillons.

Optimal kinematic dynamos in a sphere (2020)
Journal Article
Luo, J., Chen, L., Li, K., & Jackson, A. (2020). Optimal kinematic dynamos in a sphere. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 476(2233), Article 20190675. https://doi.org/10.1098/rspa.2019.0675

A variational optimization approach is used to optimize kinematic dynamos in a unit sphere and locate the enstrophy-based critical magnetic Reynolds number for dynamo action. The magnetic boundary condition is chosen to be either pseudo-vacuum or per... Read More about Optimal kinematic dynamos in a sphere.

Liouville measure as a multiplicative cascade via level sets of the Gaussian free field (2020)
Journal Article
Aru, J., Powell, E., & Sepúlveda, A. (2020). Liouville measure as a multiplicative cascade via level sets of the Gaussian free field. Annales de l'Institut Fourier, 70(1), 245-205. https://doi.org/10.5802/aif.3312

We provide new constructions of the subcritical and critical Gaussian multiplicative chaos (GMC) measures corresponding to the 2D Gaussian free field (GFF). As a special case we recover E. Aidekon’s construction of random measures using nested confor... Read More about Liouville measure as a multiplicative cascade via level sets of the Gaussian free field.

Triple linking numbers and surface systems (2020)
Journal Article

We give a refined value group for the collection of triple linking numbers of links in the 3–sphere. Given two links with the same pairwise linking numbers we show that they have the same refined triple linking number collection if and only if the li...
