Affine geometric spaces in tangent categories
R. F. Blute, G. S. H. Cruttwell, R. B. B. Lucyshyn-Wright
We continue the program of structural differential geometry that begins with the notion of a tangent category, an axiomatization of structural aspects of the tangent functor on the…
Schur multipliers and mixed unitary maps
Samuel J. Harris, Rupert H. Levene, Vern I. Paulsen +2
We consider the tensor product of the completely depolarising channel on matrices with the map of Schur multiplication by a correlation matrix and characte…
Finite distance corrections to the light deflection in a gravitational field with a plasma medium
Gabriel Crisnejo, Emanuel Gallo, Adam Rogers
The aim of the present work is twofold: first, we present general remarks about the application of recent procedures to compute the deflection angle in spherically symmetric and as…
Some notes on the robustness of k-coherence and k-entanglement
Nathaniel Johnston, Chi-Kwong Li, Sarah Plosker +2
We show that two related measures of k-coherence, called the standard and generalized robustness of k-coherence, are equal to each other when restricted to pure states. As a direct…
Smooth and sharp creation of a spherical shell for a -dimensional quantum field
Margaret E. Carrington, Gabor Kunstatter, Jorma Louko +1
We study the creation of a spherical, finite radius source for a quantized massless scalar field in 3+1 dimensions. The goal is to model the breakdown of correlations that has been…
On Operator Valued Measures
Darian McLaren, Sarah Plosker, Christopher Ramsey
We consider positive operator valued measures whose image is the bounded operators acting on an infinite-dimensional Hilbert space, and we relax, when possible, the usual assumptio…
