Critical coupling and $Δ ⟨ ϕ^{2} ⟩$ in three-dimensional $ϕ^{4}$ theory

Stephan Durr, Tolga S. H. Kiel

We consider the $ϕ^{4}$ theory with $ϕ (x) \in R$ in three Euclidean dimensions. For a variety of self-couplings $λ^$ , the critical (bare) parameter $\hatμ_{0\mathrm{c}}^2(\…

Critical coupling in $ϕ_{2}^{4}$ theory

Stephan Durr, Tolga S. H. Kiel

We consider $ϕ^{4}$ theory with $ϕ (x) \in R$ in two Euclidean dimensions. We determine for a variety of self-couplings $λ^$ the (negative) critical bare mass $\hatμ_{0\math…

Numerical study of the dimensionally reduced 3D Ising model

Tolga Kiel, Stephan Durr

We study the 3D Ising model in the infinite volume limit $N_{x, y, z} \to \infty$ by means of numerical simulations. We determine $T_{c}$ as well as the critical exponents $β, γ$ and $ν$ ,…
