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…
