A multiphase multiscale model for nutrient limited tissue growth, Part II: A simplified description (2019)
Journal Article
Holden, E., Chapman, S., Brook, B., & O'Dea, R. (2019). A multiphase multiscale model for nutrient limited tissue growth, Part II: A simplified description. ANZIAM Journal, 61(4), 368-381. https://doi.org/10.1017/S1446181119000130

In this paper, we revisit and extend our recent work (Holden et al. (2018) A multiphase multiscale model for nutrient limited tissue growth, The ANZIAM Journal, 59(4), 499-532), that considers the derivation of an effective macroscale description sui...

Pushing the limits of the reaction-coordinate mapping (2019)
Journal Article
Correa, L. A., Xu, B., Morris, B., & Adesso, G. (2019). Pushing the limits of the reaction-coordinate mapping. Journal of Chemical Physics, 151(9), Article 094107. https://doi.org/10.1063/1.5114690

The reaction-coordinate mapping is a useful technique to study complex quantum dissipative dynamics into structured environments. In essence, it aims to mimic the original problem by means of an “augmented system,” which includes a suitably chosen co... Read More about Pushing the limits of the reaction-coordinate mapping.

Extendibility of bosonic Gaussian states (2019)
Journal Article
Lami, L., Khatri, S., Adesso, G., & M. Wilde, M. (2019). Extendibility of bosonic Gaussian states. Physical Review Letters, 123(5), Article 050501. https://doi.org/10.1103/PhysRevLett.123.050501

Extendibility of bosonic Gaussian states is a key issue in continuous-variable quantum information. We show that a bosonic Gaussian state is k-extendible if and only if it has a Gaussian k-extension, and we derive a simple semidefinite program, whose...

New Semiclassical Picture of Vacuum Decay (2019)
Journal Article
Braden, J., Johnson, M. C., Peiris, H. V., Pontzen, A., & Weinfurtner, S. (2019). New Semiclassical Picture of Vacuum Decay. Physical Review Letters, 123(3), Article 031601. https://doi.org/10.1103/physrevlett.123.031601

© 2019 authors. Published by the American Physical Society. We introduce a new picture of vacuum decay which, in contrast to existing semiclassical techniques, provides a real-time description and does not rely on classically forbidden tunneling path...

Black holes, gravitational waves and fundamental physics: A roadmap (2019)
Journal Article
Askar, A., Bertone, G., Bon, E., Blas, D., Brito, R., Burrage, C., Bulik, T., Chernyakova, M., Caprini, C., Gaggero, D., Ferrari, V., Colpi, M., Gair, J., Heisenberg, L., Hendry, M., Heng, I.

Classical and Quantum Gravity, 36(14), Article 143001. https://doi.org/10.1088/1361-6382/ab0587

© 2019 IOP Publishing Ltd. The grand challenges of contemporary fundamental physics-dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-all involve gravity as a key component. And o... Read More about Black holes, gravitational waves and fundamental physics: A roadmap.

Spontaneous scalarization in generalized scalar-tensor theory (2019)
Journal Article
Andreou, N., Franchini, N., Ventagli, G., & Sotiriou, T. P. (2019). Spontaneous scalarization in generalized scalar-tensor theory. Physical Review D, 99(12), https://doi.org/10.1103/physrevd.99.124022

Spontaneous scalarization is a mechanism that endows relativistic stars and black holes with a nontrivial configuration only when their spacetime curvature exceeds some threshold. The standard way to trigger spontaneous scalarization is via a tachyon... Read More about Spontaneous scalarization in generalized scalar-tensor theory.

Classification of shift-symmetric Horndeski theories and hairy black holes (2019)
Journal Article
Saravani, M., & Sotiriou, T. P. (2019). Classification of shift-symmetric Horndeski theories and hairy black holes. Physical Review D, 99(12), Article 124004. https://doi.org/10.1103/physrevd.99.124004

No-hair theorems for scalar-tensor theories imply that the trivial scalar field configuration is the unique configuration around stationary black hole spacetimes. The most basic assumption in these theorems is that a constant scalar configuration is... Read More about Classification of shift-symmetric Horndeski theories and hairy black holes.

A dam-break driven by a moving source: a simple model for a powder snow avalanche (2019)
Journal Article
Billingham, J. (2019). A dam-break driven by a moving source: a simple model for a powder snow avalanche. Journal of Fluid Mechanics, 870, 353-388. https://doi.org/10.1017/jfm.2019.273

We study the two-dimensional, irrotational flow of an inviscid, incompressible fluid injected from a line source moving at constant speed along a horizontal boundary, into a second, immiscible, inviscid fluid of lower density. A semi-infinite, horizo... Read More about A dam-break driven by a moving source: a simple model for a powder snow avalanche.
