Detection of coherent structures in photospheric turbulent flows (2014)
Journal Article
Chian, A., Rempel, E., Aulanier, G., Schmieder, B., Shadden, S., Welsch, B., & Yeates, A. (2014). Detection of coherent structures in photospheric turbulent flows. Astrophysical Journal, 786(1), https://doi.org/10.1088/0004-637x/786/1/51

We study coherent structures in solar photospheric flows in a plage in the vicinity of the active region AR 10930 using the horizontal velocity data derived from Hinode/Solar Optical Telescope magnetograms. Eulerian and Lagrangian coherent structures... Read More about Detection of coherent structures in photospheric turbulent flows.

Growth rate of cluster algebras (2014)
Journal Article
Felikson, A., Shapiro, M., Thomas, H., & Tumarkin, P. (2014). Growth rate of cluster algebras. Proceedings of the London Mathematical Society, 109(3), 653-675. https://doi.org/10.1112/plms/pdu010

We complete the computation of growth rate of cluster algebras. In particular, we show that growth of all exceptional non-affine mutation-finite cluster algebras is exponential.

Competing p-wave orders (2014)
Journal Article
Donos, A., Gauntlett, J. P., & Pantelidou, C. (2014). Competing p-wave orders. Classical and Quantum Gravity, 31(5), https://doi.org/10.1088/0264-9381/31/5/055007

We construct electrically charged, asymptotically AdS5 black hole solutions that are dual to d = 4 CFTs in a superfluid phase with either p-wave or (p + ip)-wave order. The two types of black holes have non-vanishing charged two-form in the bulk and... Read More about Competing p-wave orders.

Simple implementation of general dark energy models (2014)
Journal Article
Bloomfield, J. K., & Pearson, J. A. (2014). Simple implementation of general dark energy models. Journal of Cosmology and Astroparticle Physics, 2014, Article 17. https://doi.org/10.1088/1475-7516/2014/03/017

We present a formalism for the numerical implementation of general theories of dark energy, combining the computational simplicity of the equation of state for perturbations approach with the generality of the effective field theory approach. An effe... Read More about Simple implementation of general dark energy models.

Computing model independent perturbations in dark energy and modified gravity (2014)
Journal Article
Battye, R. A., & Pearson, J. A. (2014). Computing model independent perturbations in dark energy and modified gravity. Journal of Cosmology and Astroparticle Physics, 2014(03), Article 051. https://doi.org/10.1088/1475-7516/2014/03/051

We present a methodology for computing model independent perturbations in dark energy and modified gravity. This is done from the Lagrangian for perturbations, by showing how field content, symmetries, and physical principles are often sufficient ing...

Implementation of a local principal curves algorithm for neutrino interaction reconstruction in a liquid argon volume (2014)
Journal Article
Back, J., Barker, G., Boyd, S., Einbeck, J., Haigh, M., Morgan, B., …Roythorne, D. (2014). Implementation of a local principal curves algorithm for neutrino interaction reconstruction in a liquid argon volume. The European Physical Journal C, 74(3), Article 2832. https://doi.org/10.1140/epjc/s10052-014-2832-4

A local principal curve algorithm has been implemented in three dimensions for automated track and shower reconstruction of neutrino interactions in a liquid argon time projection chamber. We present details of the algorithm and characterise its perf...

An infinite family of 2-groups with mixed Beauville structures (2014)
Journal Article
Barker, N., Boston, N., Peyerimhoff, N., & Vdovina, A. (2015). An infinite family of 2-groups with mixed Beauville structures. International Mathematics Research Notices, 2015(11), 3598-3618. https://doi.org/10.1093/imrn/rnu045

We construct an infinite family of triples (Gk, Hk, Tk), where Gk are 2-groups of increasing order, Hk are index 2 subgroups of Gk, and Tk are pairs of generators of Hk. We show that the triples uk = (Gk, Hk, Tk) are mixed Beauville structures if k i... Read More about An infinite family of 2-groups with mixed Beauville structures.

Representation zeta functions of nilpotent groups and generating functions for Weyl groups of type B (2014)
Journal Article
Stasinski, A., & Voll, C. (2014). Representation zeta functions of nilpotent groups and generating functions for Weyl groups of type B. American Journal of Mathematics, 136(2), 501-550. https://doi.org/10.1353/ajm.2014.0010

We study representation zeta functions of finitely generated, torsion-free nilpotent groups which are groups of rational points of unipotent group schemes over rings of integers of number fields. Using the Kirillov orbit method and $\frak{p}$-adic in... Read More about Representation zeta functions of nilpotent groups and generating functions for Weyl groups of type B.

Implications of conformal invariance in momentum space (2014)
Journal Article
Bzowski, A., McFadden, P., & Skenderis, K. (2014). Implications of conformal invariance in momentum space. Journal of High Energy Physics, 2014(03), Article 111. https://doi.org/10.1007/jhep03%282014%29111

We present a comprehensive analysis of the implications of conformal invariance for 3-point functions of the stress-energy tensor, conserved currents and scalar operators in general dimension and in momentum space. Our starting point is a novel and v... Read More about Implications of conformal invariance in momentum space.
