Nonperturbative dynamics of (2+1)d $\phi^4$-theory from Hamiltonian truncation
We use Lightcone Conformal Truncation (LCT)—a version of Hamiltonian truncation — to study the nonperturbative, real-time dynamics of ϕ$^{4}$-theory in 2+1 dimensions. This theory has UV divergences that need to be regulated. We review how, in a Hamiltonian framework with a total energy cutoff, reno...
