Qubit, operator, and gate resources required for the digitization of lattice λ ϕ 4 scalar field
theories onto quantum computers are considered, building upon the foundational work by …

The series aims to: present current and emerging innovations in GIScience; describe new
and robust GIScience methods for use in transdisciplinary problem solving and decision …

We discuss the recently developed bosonic dynamical mean-field theory (B-DMFT)
framework, which maps a bosonic lattice model onto the self-consistent solution of a bosonic …

We review recent results concerning the renormalization group (RG) transformation of
Dyson's hierarchical model (HM). This model can be seen as an approximation of a scalar …

The real time evolution of quantum field theory models can be calculated order by order in
perturbation theory. For λ ϕ 4 models, the perturbative series have a zero radius of …

We take advantage of the fact that, in λ φ 4 problems, a large field cutoff φ max makes a
perturbative series converge toward values exponentially close to the exact values to make …

Gaussian random fields have a long history in science that dates back to the research of
Andrey Kolmogorov and his group. Their investigation remains an active field of research …

A bstract We investigate the phase diagram of the compact U (1) lattice gauge theory in four
dimensions using a non-standard action which is invariant under continuous de-formations …

The divergence of perturbative expansions which occurs for the vast majority of macroscopic
systems and follows from Dyson's collapse argument prevents the direct use of Feynman's …

We consider Wilson's SU (N) lattice gauge theory (without fermions) at negative values of β=
2 N/g 2 and for N= 2 or 3. We show that in the limit β→-∞, the path integral is dominated by …
