Title: Extracting bigravity from string amplitudes Abstract: The origin of the graviton from string theory is well understood: it corresponds to a massless state in closed string spectra, whose low-energy effective action, as extracted from string scattering amplitudes,… Read More

Title: Pirogov-Sinai Theory Abstract: Pirogov-Sinai theory is a generalisation of the Peierls argument to classical spin models with non-symmetric interaction. I will first recall the Peierls argument and then consider the inhomogeneous Potts model with nearest-neighbour interaction. Pirogov-Sinai… Read More

Title: Causal Operations in Quantum Field Theory Abstract: While Quantum Field Theory is the most accurate theory we have for predicting the microscopic world, there are still open issues regarding its mathematical description. For example, the usual prescription… Read More

Title: Quantum sensing via many-body scars Abstract: Just as a hot cup of tea on your desk will eventually cool to room temperature, often a large isolated quantum system that is initially out-of-equilibrium will eventually thermalise. This process… Read More

Title: Backreacted D0/D4 background Abstract: We construct a type II A supergravity background corresponding to a backreacted D0/D4-brane system. The background is holographically dual to the Berkooz–Douglas matrix model, which was recently simulated on a lattice. The localized… Read More

Title: Holographic gauge theories on the lattice Abstract: I will first present results from our lattice studies of three-dimensional N = 8 SYM theory in the decoupling limit and finite temperatures where the gauge/gravity conjecture relates it to… Read More
