The fluid manifesto: emergent symmetries, hydrodynamics, and black holes (2016)
Journal Article
Haehl, F. M., Loganayagam, R., & Rangamani, M. (2016). The fluid manifesto: emergent symmetries, hydrodynamics, and black holes. Journal of High Energy Physics, 2016(1), Article 184. https://doi.org/10.1007/jhep01%282016%29184

We focus on the question of how relativistic fluid dynamics should be thought of as a Wilsonian effective field theory emerging from Schwinger-Keldysh path integrals. Taking the basic principles of Schwinger-Keldysh formalism seriously, we are led to... Read More about The fluid manifesto: emergent symmetries, hydrodynamics, and black holes.

On-shell Diagrams, Graßmannians and Integrability for Form Factors (2016)
Journal Article
Frassek, R., Meidinger, D., Nandan, D., & Wilhelm, M. (2016). On-shell Diagrams, Graßmannians and Integrability for Form Factors. Journal of High Energy Physics, 2016(1), Article 182. https://doi.org/10.1007/jhep01%282016%29182

We apply on-shell and integrability methods that have been developed in the context of scattering amplitudes in N=4N=4 SYM theory to tree-level form factors of this theory. Focussing on the colour-ordered super form factors of the chiral part of the... Read More about On-shell Diagrams, Graßmannians and Integrability for Form Factors.

Complex hyperbolic (3,3,n)-triangle groups (2016)
Journal Article
Parker, J. R., Wang, J., & Xie, B. (2016). Complex hyperbolic (3,3,n)-triangle groups. Pacific Journal of Mathematics, 280(2), 433-453. https://doi.org/10.2140/pjm.2016.280.433

Let p,q,rp,q,r be positive integers. Complex hyperbolic (p,q,r)(p,q,r) triangle groups are representations of the hyperbolic (p,q,r)(p,q,r) reflection triangle group to the holomorphic isometry group of complex hyperbolic space H2CHℂ2, where the gene...

The dynamics of aloof baby Skyrmions (2016)
Journal Article
Salmi, P., & Sutcliffe, P. (2016). The dynamics of aloof baby Skyrmions. Journal of High Energy Physics, 2016(1), Article 145. https://doi.org/10.1007/jhep01%282016%29145

The aloof baby Skyrme model is a (2+1)-dimensional theory with solitons that are lightly bound. It is a low-dimensional analogue of a similar Skyrme model in (3+1)-dimensions, where the lightly bound solitons have binding energies comparable to nucle...

The (2, 0) superconformal bootstrap (2016)
Journal Article
Beem, C., Lemos, M., Rastelli, L., & van Rees, B. C. (2016). The (2, 0) superconformal bootstrap. Physical Review D, 93(2), Article 025016. https://doi.org/10.1103/physrevd.93.025016

We develop the conformal bootstrap program for six-dimensional conformal field theories with (2, 0) supersymmetry, focusing on the universal four-point function of stress tensor multiplets. We review the solution of the superconformal Ward identities... Read More about The (2, 0) superconformal bootstrap.

DC conductivity of magnetised holographic matter (2016)
Journal Article
Donos, A., Gauntlett, J., Griffin, T., & Melgar, L. (2016). DC conductivity of magnetised holographic matter. Journal of High Energy Physics, 2016(1), Article 113. https://doi.org/10.1007/jhep01%282016%29113

We consider general black hole solutions of Einstein-Maxwell-scalar theory that are holographically dual to conformal field theories at finite charge density with nonvanishing magnetic fields and local magnetisation currents, which generically break...

On the cohomology of linear groups over imaginary quadratic fields (2016)
Journal Article
Dutour Sikirić, M., Gangl, H., Gunnells, P. E., Hanke, J., Schürmann, A., & Yasaki, D. (2016). On the cohomology of linear groups over imaginary quadratic fields. Journal of Pure and Applied Algebra, 220(7), 2564-2589. https://doi.org/10.1016/j.jpaa.2015.12.002

Let Γ be the group GLN(OD), where OD is the ring of integers in the imaginary quadratic field with discriminant D<0. In this paper we investigate the cohomology of Γ for N=3,4 and for a selection of discriminants: D≥−24 when N=3, and D=−3,−4 when N=4...

Stellar coronal response to differential rotation and flux emergence (2016)
Journal Article
Gibb, G., Mackay, D., Jardine, M., & Yeates, A. (2016). Stellar coronal response to differential rotation and flux emergence. Monthly Notices of the Royal Astronomical Society, 456(4), 3624-3637. https://doi.org/10.1093/mnras/stv2920

We perform a numerical parameter study to determine what effect varying differential rotation and flux emergence has on a star's non-potential coronal magnetic field. In particular we consider the effects on the star's surface magnetic flux, open mag... Read More about Stellar coronal response to differential rotation and flux emergence.

Exclusive physics at the LHC with SuperChic 2 (2016)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2016). Exclusive physics at the LHC with SuperChic 2. The European Physical Journal C, 76(1), Article 9. https://doi.org/10.1140/epjc/s10052-015-3832-8

We present a range of physics results for central exclusive production processes at the LHC, using the new SuperChic 2 Monte Carlo event generator. This includes significant theoretical improvements and updates, most importantly a fully differential... Read More about Exclusive physics at the LHC with SuperChic 2.
