Studying IR Dynamics with Conformal Truncation

I will discuss recent work on using conformal Hamiltonian truncation methods to study strongly coupled QFTs. In this method, CFT data is used to perform controlled, numerical computations in strongly coupled QFTs, in any spacetime dimension. We test our framework in a 1+1 dimensional setting in the RG flow to the Ising model. We compute non-perturbative spectral densities of several local operators, which are equivalent to real-time, infinite-volume correlation functions. I'll also talk about ongoing work in 2+1 dimensions.
