Meet the kowari: a pint-sized predator on the fast track to extinction
Blink and you’ll miss it. The kowari is a charismatic marsupial carnivore that needs our help.

Modeling the effects of perturbations and steepest entropy ascent on the time evolution of entanglement
This work presents an analysis of the evolution of perturbed Bell diagonal states using the equation of motion of steepest-entropy-ascent quantum thermodynamics (SEAQT), the Lindblad equation, and various measures of loss of entanglement. First, a brief derivation is presented showing that Bell diagonal states are stationary states that are not stable equilibrium states relative to the SEAQT equation of motion, highlighting the need for the development of perturbation methods to study the evolu…

CeeDee Lamb not present at start of Cowboys' voluntary offseason workouts
With no extension in sight, Dallas Cowboys wide receiver CeeDee Lamb made himself scarce as the team opened voluntary offseason workouts this week. Lamb is not at the first day of the offseason program on Monday, NFL Network Insider Ian Rapoport reported.

Exponentially localised interface eigenmodes in finite chains of resonators
This paper studies wave localisation in chains of finitely many resonators. There is an extensive theory predicting the existence of localised modes induced by defects in infinitely periodic systems. This work extends these principles to finite-sized systems. We consider finite systems of subwavelength resonators arranged in dimers that have a geometric defect in the structure. This is a classical wave analogue of the Su-Schrieffer-Heeger model. We prove the existence of a spectral gap for defe…

Superspecial genus-$4$ double covers of elliptic curves
In this paper we study genus-$4$ curves obtained as double covers of elliptic curves. Firstly we give explicit defining equations of such curves with explicit criterion for whether it is nonsingular, and show the irreducibility of the long polynomial determining whether the curve is nonsingular, in any characteristic $\ne 2,3$. Secondly as an application we enumerate superspecial genus-$4$ double covers of elliptic curves in small characteristic.

Exploring Multiscale Quantum Media: High-Precision Efficient Numerical Solution of the Fractional Schrödinger equation, Eigenfunctions with Physical Potentials, and Fractionally-Enhanced Quantum Tunneling
Fractional evolution equations lack generally accessible and well-converged codes excepting anomalous diffusion. A particular equation of strong interest to the growing intersection of applied mathematics and quantum information science and technology is the fractional Schrödinger equation, which describes sub-and super-dispersive behavior of quantum wavefunctions induced by multiscale media. We derive a computationally efficient sixth-order split-step numerical method to converge the eigenfun…

Chapter: Vulnerability of Quantum Information Systems to Collective Manipulation
The highly specialist terms `quantum computing' and `quantum information', together with the broader term `quantum technologies', now appear regularly in the mainstream media. While this is undoubtedly highly exciting for physicists and investors alike, a key question for society concerns such systems' vulnerabilities -- and in particular, their vulnerability to collective manipulation. Here we present and discuss a new form of vulnerability in such systems, that we have identified based on det…
