Entanglement Detection by Local Orthogonal Observables
We propose a family of entanglement witnesses and corresponding positive maps
that are not completely positive based on local orthogonal observables. As
applications the entanglement witness of the bound entangled state
[P. Horodecki, Phys. Lett. A {\bf 232}, 333 (1997)] is explicitly constructed
and a family of -dimensional bound entangled states is designed so that the
entanglement can be detected by permuting local orthogonal observables. Further
the proposed physically not implementable positive maps can be physically
realized by measuring a Hermitian correlation matrix of local orthogonal
observables.Comment: 4 pages, 1 figur
Dark necessities? Candidates’ aversive personality traits and negative campaigning in the 2018 American Midterms
Are candidates with “dark” personality profiles more likely to go negative? We triangulate data for the 2018 Senate Midterms in the United States from two independent sources (the automated coding of social media posts and an expert survey) and test the extent to which the candidates’ “dark” personality traits (narcissism, psychopathy, and Machiavellianism) are associated with their negativity and incivility. By and large, we find that this is the case, especially when combining the separate traits into broader indicators of “dark” personality (“dark core” and underlying personality dimensions). These results resist robustness checks via models run with alternative specifications, such as using measures of personality (and campaign) that are adjusted to filter out the ideological profile of experts, additional covariates, more restrictive modelling, and alternative measurement of key dependent variables
