Physics Group Meeting

We present constraints on non-local primordial non-Gaussianity (NLPNG) from the Baryon Oscillation Spectroscopic Survey data. We first review how NLPNG arises in single-field inflationary models. We then review the Effective Field Theory of Large...

Computing non-protected observables in AdS/CFT in presence of RR background fluxes is notoriously hard. For the spectrum of integrable backgrounds, Bethe ansatz techniques provide a framework for doing so. For correlation functions, the hexagon...

 I shall present joint work with Maxim Kontsevich (arXiv:2105.10161) describing an interesting domain of complex metrics on a smooth manifold. It is a complexification of the space of ordinary Riemannian metrics, and has the Lorentzian metrics (but...

There is a Narain CFT naturally associated to any self-dual quantum stabilizer code.  For these "code CFTs", the constraints of modular invariance reduce to simple algebraic equations satisfied by the enumerator polynomial of the code, which can be...

 I will explain how the conformal bootstrap can be adapted to place rigorous bounds on the spectra of automorphic forms on locally symmetric spaces. A locally symmetric space is of the form H\G/K, where G is a non-compact semisimple Lie group, K the...

I will introduce the topic of heavy multiquark states, with special attention to the current theoretical and experimental status. I will first review the available experimental information and then discuss them in the context of the two most likely...

We discuss the possible transition between string scale black holes and self gravitating fundamental strings. We find evidence for a smooth transition in the heterotic string case while in the type II case they cannot be connected as classical...
