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: 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
