Poster session and dinner. Dinner is takeaway pizza
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...
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...
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,...
Semileptonic Charm Decays on the Lattice
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...
