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, April). Learning Multimodal VAEs Through Mutual Supervision. Presented at ICLR 2022: The Tenth International Conference on Learning Representations, Virtual

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.

Non-invertible global symmetries and completeness of the spectrum (2021)
Journal Article
Heidenreich, B., McNamara, J., Montero, M., Reece, M., Rudelius, T., & Valenzuela, I. (2021). Non-invertible global symmetries and completeness of the spectrum. Journal of High Energy Physics, 2021(9), Article 203. https://doi.org/10.1007/jhep09%282021%29203

It is widely believed that consistent theories of quantum gravity satisfy two basic kinematic constraints: they are free from any global symmetry, and they contain a complete spectrum of gauge charges. For compact, abelian gauge groups, completeness... Read More about Non-invertible global symmetries and completeness of the spectrum.

Entropy of thermal CFTs on curved backgrounds (2021)
Journal Article
Giataganas, D., & Tetradis, N. (2021). Entropy of thermal CFTs on curved backgrounds. Physical Review D, 104(6), https://doi.org/10.1103/physrevd.104.066024

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)
Journal Article
Dorey, P., Gorina, A., Perapechka, I., Romańczukiewicz, T., & Shnir, Y. (2021). Resonance structures in kink-antikink collisions in a deformed sine-Gordon model. Journal of High Energy Physics, 2021(9), Article 145. https://doi.org/10.1007/jhep09%282021%29145

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.

Rademacher-type theorems and Sobolev-to-Lipschitz properties for strongly local Dirichlet spaces (2021)

We extensively discuss the Rademacher and Sobolev-to-Lipschitz properties for generalized intrinsic distances on strongly local Dirichlet spaces possibly without square field operator. We present many non-smooth and infinite-dimensional examples. As... Read More about Rademacher-type theorems and Sobolev-to-Lipschitz properties for strongly local Dirichlet spaces.
