We examine the current state-of-the-art in nonperturbative calculations done with
Hamiltonians constructed in light-front quantization of various field theories. The language of …

We defend the Fock-space Hamiltonian truncation method, which allows us to calculate
numerically the spectrum of strongly coupled quantum field theories, by putting them in a …

We study the second-order quantum phase transition of massive real scalar field theory with
a quartic interaction in (1+ 1) dimensions on an infinite spatial lattice using matrix product …

A bstract We make a detailed analysis of the spontaneous Z 2-symmetry breaking in the two
dimensional real ϕ 4 theory with the tensor renormalization group approach, which allows …

We both review and augment the lightcone conformal truncation (LCT) method. LCT is a
Hamiltonian truncation method for calculating dynamical quantities in QFT in infinite volume …

Hamiltonian truncation (also known as “truncated spectrum approach”) is a numerical
technique for solving strongly coupled quantum field theories, in which the full Hilbert space …

continuum 4 theory Page 1 Monte Carlo simulation calculation of the critical coupling constant for …

We use lattice formulation of ϕ 4 theory in order to investigate nonperturbative features of its
continuum limit in two dimensions. In particular, by means of Monte Carlo calculations, we …

We use Monte Carlo simulations to obtain an improved lattice measurement of the critical
coupling constant [λ/μ 2] crit for the continuum (1+ 1)-dimensional (λ/4) ϕ 4 theory. We find …

A bstract We study 1+ 1 dimensional ϕ 4 theory using the recently proposed method of
conformal truncation. Starting in the UV CFT of free field theory, we construct a complete …
