8. Quantum corrections to the density of states of near-extremal black holes

Recent work by Turiaci, Iliesiu, and others has identified quantum corrections to the density of states of near-extremal black holes. These corrections have significant implications for our understanding of black-hole physics (and physics of strongly interacting QFT) in the very-low-temperature regime. In this talk, I will present the latest findings and outline some directions for future research.

9. Holography from the lattice

I will discuss how lattice techniques can be used to explore simple quantum field theories that are relevant to holography. By focusing on lower-dimensional models with strong coupling and large N limits, such as matrix quantum mechanics, supersymmetric gauge theories, and scalar models with emergent geometry, we can probe aspects of holography from first principles. The aim is to identify...

10. Centres of symmetric group algebras in gauge string duality

The study of half-BPS states of dimension n in N = 4 super-Yang Mills theory with U (N ) gauge group has motivated the study of interesting subsets of conjugacy classes of the symmetric group which multiplicatively generate the centre of the symmetric group algebra. In this talk, I will outline some current and future developments in the study of structural properties of this algebra.

11. Quantum field theory in small systems

Recent advances in results from high-energy QCD and AMO suggest that non-trivial, many-body dynamics emerge at astonishingly low numbers of particles and in systems of shockingly small size. My group has been and will continue to think about the theoretical predictions for such systems nominally so far away from the thermodynamic limit.

12. AdS/CFT, string theory, and black holes”

Currently I am looking at what we can learn about QFT in de Sitter space by embedding it as a boundary CFT in AdS, features of black hole attractors that have been heated up and Spindle solutions in SUGRA and their holography.
