Phase-field modelling of the effect of density change on solidification revisited: Model development and analytical solutions for single component materials

Gyula I. Toth, Wenyue Ma

In this paper the development of a physically consistent phase-field theory of solidification shrinkage is presented. The coarse-grained hydrodynamic equations are derived directly…

Lower Dimensional Kernels for Video Discriminators

Emmanuel Kahembwe, Subramanian Ramamoorthy

This work presents an analysis of the discriminators used in Generative Adversarial Networks (GANs) for Video. We show that unconstrained video discriminator architectures induce a…

Ozone chemistry on tidally locked M dwarf planets

Jack S. Yates, Paul I. Palmer, James Manners +4

We use the Met Office Unified Model to explore the potential of a tidally locked M dwarf planet, nominally Proxima Centauri b irradiated by a quiescent version of its host star, to…

Debye-Hückel potential at an interface between two media

Alexander Morozov, Iain Muntz, Job H. J. Thijssen +1

Electrostatic interactions between point charges embedded into interfaces separating dielectric media are omnipresent in soft matter systems and often control their stability. Such…

An exploratory study of heavy-light semileptonic form factors using distillation

Peter Boyle, Felix Erben, Michael Marshall +3

We present our exploratory study with the aim of simulating heavy-light semileptonic form factors as part of the RBC-UKQCD charm (to bottom) physics programme. We are using a disti…

Kinetic roughening in active interfaces

Francesco Cagnetta, Martin R. Evans, Davide Marenduzzo

The essential features of many interfaces driven out of equilibrium are described by the same equation---the Kardar-Parisi-Zhang (KPZ) equation. How do living interfaces, such as t…

Diagrammatic Coaction of Two-Loop Feynman Integrals

Samuel Abreu, Ruth Britto, Claude Duhr +2

It is known that one-loop Feynman integrals possess an algebraic structure encoding some of their analytic properties called the coaction, which can be written in terms of Feynman…
