Learning Multimodal VAEs Through Mutual Supervision (2021)
Presentation / Conference Contribution
Joy, T., Shi, Y., Torr, P. H., Rainforth, T., Schmon, S. M., & Siddharth, N. (2022). Learning Multimodal VAEs Through Mutual Supervision.

Multimodal VAEs seek to model the joint distribution over heterogeneous data (e.g.\ vision, language), whilst also capturing a shared representation across such modalities. Prior work has typically combined information from the modalities by reconcil... Read More about Learning Multimodal VAEs Through Mutual Supervision.

Entropy of thermal CFTs on curved backgrounds (2021)
Journal Article

We use holography in order to study the entropy of thermal conformal field theory (CFT) on (1 þ 1)- dimensional curved backgrounds that contain horizons. Starting from the metric of the BañadosTeitelboim-Zanelli (BTZ) black hole, we perform explicit... Read More about Entropy of thermal CFTs on curved backgrounds.

Resonance structures in kink-antikink collisions in a deformed sine-Gordon model (2021)

We study kink-antikink collisions in a model which interpolates smoothly between the completely integrable sine-Gordon theory, the ϕ4 model, and a ϕ6-like model with three degenerate vacua. We find a rich variety of behaviours, including integrabilit... Read More about Resonance structures in kink-antikink collisions in a deformed sine-Gordon model.

Dissipation in holographic superfluids (2021)
Journal Article
Donos, A., Kailidis, P., & Pantelidou, C. (2021). Dissipation in holographic superfluids. Journal of High Energy Physics, 2021(9), Article 134. https://doi.org/10.1007/jhep09%282021%29134

We study dissipation in holographic superfluids at finite temperature and zero chemical potential. The zero overlap with the heat current allows us to isolate the physics of the conserved current corresponding to the broken global U(1). By using anal...

Elastic photon-initiated production at the LHC: the role of hadron-hadron interactions (2021)
Journal Article

We analyse in detail the role of additional hadron–hadron interactions in elastic photon– initiated (PI) production at the LHC, both in p p and heavy ion collisions. We first demonstrate that the source of difference between our predictions and other... Read More about Elastic photon-initiated production at the LHC: the role of hadron-hadron interactions.

Operator lifetime and the force-free electrodynamic limit of magnetised holographic plasma (2021)
Journal Article

Using the framework of higher-form global symmetries, we examine the regime of validity of force-free electrodynamics by evaluating the lifetime of the electric field operator, which is non-conserved due to screening effects. We focus on a holographi... Read More about Operator lifetime and the force-free electrodynamic limit of magnetised holographic plasma.

Instanton worldlines in five-dimensional Ω-deformed gauge theory (2021)
Journal Article

We discuss the Bosonic sector of a class of supersymmetric non-Lorentzian five-dimensional gauge field theories with an SU(1,3) conformal symmetry. These actions have a Lagrange multiplier which imposes a novel Ω-deformed anti-self-dual gauge field c... Read More about Instanton worldlines in five-dimensional Ω-deformed gauge theory.

Hunting for QCD instantons at the LHC in events with large rapidity gaps (2021)
Journal Article

We outline a strategy of how to search for QCD instantons of invariant mass 20–60 GeVin diffractive events in low-luminosity runs at the LHC. We show that, by imposing appropriate selection criteria on the final states, one can select the kinematic r...

Reliability analysis for systems based on degradation rates and hard failure thresholds changing with degradation levels (2021)

Degradation-shock failure processes widely exist in practice, and extensive work has been carried out to better describe such processes. In this paper, a new model is developed for reliability analysis of systems subject to dependent degradation-shoc...

Spectral walls in multifield kink dynamics (2021)
Journal Article

We show that spectral walls are common phenomena in the dynamics of kinks in (1+1) dimensions. They occur in models based on two or more scalar fields with a nonempty Bogomol’nyi-Prasad-Sommerfield (BPS) sector, hosting two zero modes, where they are...

We investigate rough differential equations with a time-dependent reflecting lower barrier, where both the driving (rough) path and the barrier itself may have jumps. Assuming the driving signals allow for Young integration, we provide existence, uni... Read More about Càdlàg rough differential equations with reflecting barriers.
