A Model of Polarisation Rotations in Blazars from Kink Instabilities in Relativistic Jets
Galaxies, 2017 This paper presents a simple model of polarisation rotation in optically thin relativistic jets of blazars. The model is based on the development of helical (kink) mode of current-driven instability.

The Economic Journal, 2022 Abstract We document the emergence of spatial polarisation in the United States during the 1980–2008 period. This phenomenon is characterised by stronger employment polarisation in larger cities, both at the occupational and the worker levels.

Conflict and polarisation on social media caused by the Russia-Ukraine War: The case of Ekşi Sözlük
Connectist Istanbul University Journal of Communication Sciences, 2023 There has been an increase in ideological and political polarisation in Türkiye. Society is divided into dichotomies such as modern-traditional, religious-secular, right-left, Turkish-Kurdish, and Sunni-Alawi; the distinction is not limited to these. The

Current Biology, 2011 SummaryPutting on a pair of polarised sunglasses is as close as most of us get to seeing polarised light. Photographers also use polarising filters and, in both cases, the reason for placing such filters in front of eye or camera is to reduce glare and increase contrast within the image or scene viewed.

A polarisation‐analysing CMOS image sensor for sensitive polarisation modulation detection
Electronics Letters, 2021 In this study, a polarisation‐analysing CMOS image sensor is fabricated for sensitive polarisation modulation detection. Although the image sensor with on‐pixel polarisers can image the incident polarisation collectively, its sensitivity to a weak ...

SU(2) symmetry of coherent photons and application to Poincaré rotator
Frontiers in Physics, 2023 Lie algebra is a hidden mathematical structure behind various quantum systems realised in nature. Here, we consider SU(2) wavefunctions for polarisation states of coherent photons emitted from a laser source, and discuss the relationship to spin ...

Combinatorics, Probability and Computing, 2023 AbstractIn this paper we study a variation of the random $k$ -SAT problem, called polarised random $k$ -SAT, which contains both the classical random $k$ -SAT model and the random version of monotone $k$ -SAT another well-known NP-complete version of SAT.
