76. Optimisation on Riemannian Manifolds & Quantum Algorithms

Andres Arcia Lopez

17/12/2025, 19:00

The design of new quantum algorithms remains an unintuitive and elusive area that has lagged behind the rest of the developments of quantum computing. Despite decades of research, we have developed very few quantum techniques, in part due to the lack of a unifying framework to aid our understanding of existing ones and to facilitate the design of new ones. A promising route, particularly...

80. Supersymmetric AdS Solitons, Coulomb Branch Flows, Twisted Compactifications and their Marginal Deformations

Madi Hammond (Swansea University)

17/12/2025, 19:20

I will speak about the papers https://arxiv.org/pdf/2506.10062v3 and another two to appear shortly.

We construct and analyse infinite classes of regular supergravity backgrounds dual to four-dimensional SCFTs compactified on a circle
with a supersymmetry-preserving twist. These flows lead to three-dimensional gapped QFTs preserving four supercharges. The solutions arise in Type IIB, Type...

98. Linking Leptogenesis and Asymmetric Dark Matter

Henry McKenna (The University of Liverpool)

We investigate a minimal extension of the Leptogenesis framework that simultaneously explains the observed baryon asymmetry and dark matter (DM) abundance through the decay of a heavy Majorana neutrino. In this scenario, CP violation arises from complex Yukawa couplings, enabling the generation of asymmetries in both the Standard Model (SM) and DM sectors. We explore two regimes: (i) wash-in,...

99. Black hole hair transplant with ultra light dark matter

Dhruv Pathak (King's College London)

You can create a black hole bomb using a Kerr black hole by putting mirrors around it. This can happen because of a phenomenon called superradiance using which an incident wave can get reflected back with larger energy. The mirror then reflects it back and you can keep on extracting energy until the limit is reached. For a massive field, the mass itself acts as a natural barrier. Ultra light...

85. M-Theory Through Matrix Models

Martin Winterlich (Dublin Institute for Advanced Studies and Trinity College Dublin)

A compelling quantum theory of gravity should provide a geometrically intuitive framework, continuing the tradition established by Einstein’s insight that geometry and physics are inseparable. String theory extends this legacy by replacing point-like structures with fundamentally extended objects, offering a richer geometric vocabulary and a natural setting in which causality and topology...

103. p-form Generalised Symmetries in Gauge Theories

Ben Cooper

In recent years, it has been shown that symmetries in quantum field theory extend beyond their action on familiar pointlike operators to include generalised symmetries acting on extended objects. In this talk, I introduce the framework of generalised symmetries, with an emphasis on 1-form and, more generally, p-form symmetries, and explain how they naturally arise in gauge theories. In Maxwell...
