Computing the Critical Temperature of the Affine-Transformed Ising Model Using Masked Autoregressive Flow
Kai Svenson, George T. Fleming, Richard C. Brower +2
The simple Ising model provides a rich environment to build and study lattice field theories. As part of an ongoing project to construct a conformal field theory (CFT) on an arbitr…
Studying with radial quantization on the lattice: Free limit
Peter A. Boyle, Richard C. Brower, George T. Fleming +3
To investigate the three-dimensional quantum electrodynamics in the radial quantization on the lattice, the lattice action is constructed and the free limit is studied on $S^2 \tim…
Ising on -- The Affine Conjecture
Richard C. Brower, George T. Fleming, Jin-Yun Lin +2
We review the recent construction \cite{brower2024isingmodelmathbbs2} of the 2d Ising model on a triangulated sphere . Surprisingly, this led to a precise map of the…
Energy-momentum tensor in the 2D Ising CFT in full modular space
Richard C. Brower, George T. Fleming, Nobuyuki Matsumoto +1
A set of lattice operators for the energy-momentum (EM) tensor in the Ising CFT is derived in the spin variables. Our expression works under arbitrary affine transformation both on…
Decimation map in 2D for accelerating HMC
Nobuyuki Matsumoto, Richard C. Brower, Taku Izubuchi
To accelerate the HMC with field transformation, we consider a variant of the trivializing map, the decimation map, which can be regarded as a coarse-graining transformation. Using…
