BPS solutions for generalised Wess-Zumino models and their applications (2019)
Journal Article
Abel, S., Bonnefoy, Q., & Chowdhury, D. (2019). BPS solutions for generalised Wess-Zumino models and their applications. Journal of High Energy Physics, 2019(10), Article 242. https://doi.org/10.1007/jhep10%282019%29242

We present BPS solutions to a general class of Wess-Zumino models which ex- tend previous results in the literature. We discuss their relation to amplitudes on threshold, and their application to scalar domain walls in Supersymmetric QCD. We also fin...

Stability and Vacuum Energy in Open String Models with Broken Supersymmetry (2019)
Journal Article
Abel, S., Dudas, E., Lewis, D., & Partouche, H. (2019). Stability and Vacuum Energy in Open String Models with Broken Supersymmetry. Journal of High Energy Physics, 2019(10), Article 226. https://doi.org/10.1007/jhep10%282019%29226

We construct type I string models with supersymmetry broken by compactifi- cation that are non-tachyonic and have exponentially small effective potential at one-loop. All open string moduli can be stabilized, while the closed string moduli remain mas... Read More about Stability and Vacuum Energy in Open String Models with Broken Supersymmetry.

On Mirror Maps for Manifolds of Exceptional Holonomy (2019)
Journal Article
Braun, A. P., Majumder, S., & Otto, A. (2019). On Mirror Maps for Manifolds of Exceptional Holonomy. Journal of High Energy Physics, 2019(10), Article 204. https://doi.org/10.1007/jhep10%282019%29204

We study mirror symmetry of type II strings on manifolds with the exceptional holonomy groups G2 and Spin(7). Our central result is a construction of mirrors of Spin(7) manifolds realized as generalized connected sums. In parallel to twisted connecte...

Hydrodynamics of broken global symmetries in the bulk (2019)
Journal Article
Donos, A., Martin, D., Pantelidou, C., & Ziogas, V. (2019). Hydrodynamics of broken global symmetries in the bulk. Journal of High Energy Physics, 2019(10), Article 218. https://doi.org/10.1007/jhep10%282019%29218

We consider holographic theories at finite temperature in which a continuous global symmetry in the bulk is spontaneously broken. We study the linear response of operators in a regime which is dual to time dependent, long wavelength deformations of s... Read More about Hydrodynamics of broken global symmetries in the bulk.

IIB flux non-commutativity and the global structure of field theories (2019)
Journal Article
García Etxebarria, I., Heidenreich, B., & Regalado, D. (2019). IIB flux non-commutativity and the global structure of field theories. Journal of High Energy Physics, 2019(10), Article 169. https://doi.org/10.1007/jhep10%282019%29169

We discuss the origin of the choice of global structure for six dimensional (2, 0) theories and their compactifications in terms of their realization from IIB string theory on ALE spaces. We find that the ambiguity in the choice of global structure o... Read More about IIB flux non-commutativity and the global structure of field theories.

Young supertableaux and the large N = 4 superconformal algebra (2019)
Journal Article
Fearn, S. (2019). Young supertableaux and the large N = 4 superconformal algebra. Physica Scripta, 94(12), Article 125222. https://doi.org/10.1088/1402-4896/ab3b29

In this paper we consider representations of the ‘Large’ N = 4 superconformal algebra A in the Ramond sector as infinite-dimensional graded modules of its zero mode subalgebra, which we show to be the finite superalgebra su(2j2). We describe how repr... Read More about Young supertableaux and the large N = 4 superconformal algebra.

Conical holographic heat engines (2019)
Journal Article
Ahmed, W., Chen, H. Z., Gesteau, E., Gregory, R., & Scoins, A. (2019). Conical holographic heat engines. Classical and Quantum Gravity, 36(21), https://doi.org/10.1088/1361-6382/ab470b

We demonstrate that adding a conical deficit to a black hole holographic heat engine increases its efficiency; in contrast, allowing a black hole to accelerate decreases efficiency if the same average conical deficit is maintained. Adding other charg... Read More about Conical holographic heat engines.
