Which processes dominate visual search: Bottom-up feature contrast, top-down tuning or trial history? (2023)
Journal Article
Becker, S. I., Grubert, A., Horstmann, G., & Ansorge, U. (2023). Which processes dominate visual search: Bottom-up feature contrast, top-down tuning or trial history?. Cognition, 236, Article 105420. https://doi.org/10.1016/j.cognition.2023.105420

Previous research has identified three mechanisms that guide visual attention: bottom-up feature contrasts, top-down tuning, and the trial history (e.g., priming effects). However, only few studies have simultaneously examined all three mechanisms. H...

Graviton trispectrum from gluons (2023)
Journal Article
Armstrong, C., Goodhew, H., Lipstein, A., & Mei, J. (2023). Graviton trispectrum from gluons. Journal of High Energy Physics, 2023(8), Article 206. https://doi.org/10.1007/jhep08%282023%29206

The tree-level wavefunction coefficient for four gravitons in de Sitter space was recently bootstrapped using the Cosmological Optical Theorem, flat space limit, and Manifestly Local Test [1]. Inspired by the double copy for scattering amplitudes, we... Read More about Graviton trispectrum from gluons.

A Goldstone theorem for continuous non-invertible symmetries (2023)
Journal Article
Etxebarria, I. G., & Iqbal, N. (2023). A Goldstone theorem for continuous non-invertible symmetries. Journal of High Energy Physics, 2023(9), Article 145. https://doi.org/10.1007/jhep09%282023%29145

We study systems with an Adler-Bell-Jackiw anomaly in terms of non-invertible symmetry. We present a new kind of non-invertible charge defect where a key role is played by a local current operator localized on the defect. The charge defects are now l...

Two Magnon Scattering Contribution to the Ferromagnetic Resonance Linewidth of Pt(Ir)/CoFeTaB/Ir(Pt) Thin Films (2023)
Journal Article
Tokaç, M., Kazan, S., Özkal, B., Al-jawfi, N., Rameev, B., Nicholson, B., & Hindmarch, A. T. (2023). Two Magnon Scattering Contribution to the Ferromagnetic Resonance Linewidth of Pt(Ir)/CoFeTaB/Ir(Pt) Thin Films. Applied Magnetic Resonance, 54(10), 1053-1064. https://doi.org/10.1007/s00723-023-01601-3

The magnetic properties of Pt/CoFeTaB/Ir and Ir/CoFeTaB/Pt trilayer thin films have been studied using angular- and temperature-dependent ferromagnetic resonance. This enables quantitative determination of the various contributions to the magnetic be...
