The Effects of Metallicity on Convective Overshoot Behaviour in Models of delta Scuti Variable Stars

V. Dornan, C. C. Lovekin

delta Scuti variables are stars which exhibit periodic changes in their luminosity through radial and non-radial pulsations. Internally, these stars have relatively small convectiv…

Five years of BRITE-Constellation photometry of the luminous blue variable P Cygni: properties of the stochastic low-frequency variability

Ashley Elliott, Noel D. Richardson, Herbert Pablo +9

Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf-Rayet stars. The variability of these…

Completely positive completely positive maps (and a resource theory for non-negativity of quantum amplitudes)

Nathaniel Johnston, Jamie Sikora

In this work we examine quantum states which have non-negative amplitudes (in a fixed basis) and the channels which preserve them. These states include the ground states of stoquas…

Birkhoff-James Orthogonality in the Trace Norm, with Applications to Quantum Resource Theories

Nathaniel Johnston, Shirin Moein, Rajesh Pereira +1

We develop numerous results that characterize when a complex Hermitian matrix is Birkhoff-James orthogonal, in the trace norm, to a (Hermitian) positive semidefinite matrix or set…

Spectral Properties of Symmetric Quantum States and Symmetric Entanglement Witnesses

Gabriel Champagne, Nathaniel Johnston, Mitchell MacDonald +1

We introduce and explore two questions concerning spectra of operators that are of interest in the theory of entanglement in symmetric (i.e., bosonic) quantum systems. First, we in…

Hadron spectroscopy using the light-front holographic Schrödinger equation and the 't Hooft equation

Mohammad Ahmady, Satvir Kaur, Sugee Lee MacKay +2

Light-front holographic QCD provides a successful first approximation to hadron spectroscopy in the chiral limit of -dim light-front QCD, where a holographic Schrödinger-lik…

Space Photometry with BRITE-Constellation

Weiss W. W, Zwintz K., Kuschnig R. +16

BRITE-Constellation is devoted to high-precision optical photometric monitoring of bright stars, distributed all over the Milky Way, in red and/or blue passbands. Photometry from s…

TESS Cycle 1 observations of roAp stars with 2-min cadence data

D. L. Holdsworth, M. S. Cunha, D. W. Kurtz +41

We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…

Nucleon electroweak form factors using spin-improved holographic light-front wavefunctions

Mohammad Ahmady, Dipankar Chakrabarti, Chandan Mondal +1

We construct spin-improved holographic light front wavefunctions for the nucleons (viewed as quark-diquark systems) and use them to successfully predict their electromagnetic Sachs…

Extending light-front holographic QCD using the 't Hooft Equation

Mohammad Ahmady, Harleen Dahiya, Satvir Kaur +3

We show the 't Hooft Equation and the light-front holographic Schrödinger Equation are complementary to each other in governing the transverse and longitudinal dynamics of colour c…

Single Production Off Neutrons Bound in Deuteron with Linearly Polarized Photons

C. Mullen, S. Gardner, D. I. Glazier +79

The quasifree photon beam asymmetry, , has been measured at photon energies, , from 390 to 610 MeV, corresponding to center of mass energy fr…

Categorical semantics of a simple differential programming language

Geoffrey Cruttwell, Jonathan Gallagher, Dorette Pronk

With the increased interest in machine learning, and deep learning in particular, the use of automatic differentiation has become more wide-spread in computation. There have been t…

The more legs the merrier: A new composition for symmetric (multi-)lenses

Michael Johnson, Robert Rosebrugh

Lenses are a category theoretic construct and are used in a wide variety of applications. Symmetric lenses compose to, of course, form new symmetric lenses. Symmetric lenses are us…
