Solving strongly-coupled RG flows via exact diagonalization
Lorenzo Vitale (EPFL)


We present a new class of numerical methods, dubbed "Hamiltonian truncation", to solve the IR dynamics of strongly-coupled QFTs.
We report on the promising results of our early studies, where we apply these techniques to the Phi^4 theory in 2D.
Finally, we outline a few research directions to make "Hamiltonian truncation" a powerful tool to solve strongly-coupled RG flows in any dimension.
