• Title: Scaled Affine Quantization of Ultralocal $\varphi^4_2$ a comparative Path Integral Monte Carlo study with Canonical Quantization
• Authors: Riccardo Fantoni and John R. Klauder
• Abstract summary: We show that $r geq 2n/(n-2) can be acceptably quantized and the resulting theory is nontrivial, unlike what happens using canonical quantization. In particular we consider the ultralocal $varphi4$ model and its renormalized properties for both the scaled canonical quantization and the scaled affine quantization version.

• Abstract: After the success of affine quantization in proving through Monte Carlo analysis that the covariant euclidean scalar field theory, $\varphi^r_n$, where $r$ denotes the power of the interaction term and $n = s + 1$ with $s$ the spatial dimension and $1$ adds imaginary time, such that $r \geq 2n/(n-2)$ can be acceptably quantized and the resulting theory is nontrivial, unlike what happens using canonical quantization, we show here that the same has to be expected for $r>2$ and any $n$ even for the ultralocal field theory. In particular we consider the ultralocal $\varphi^4_2$ model and study its renormalized properties for both the scaled canonical quantization version and the scaled affine quantization version through path integral Monte Carlo.

  We provide a systematic treatment of boundaries based on subgroups $Ksubseteq G$ with the Kitaev quantum double $D(G)$ model in the bulk. The boundary sites are representations of a $*$-subalgebra $Xisubseteq D(G)$ and we explicate its structure as a strong $*$-quasi-Hopf algebra. As an application of our treatment, we study patches with boundaries based on $K=G$ horizontally and $K=e$ vertically and show how these could be used in a quantum computer
