Lorentzian OPE Inversion Formula: A Geometric Perspective
Pulkit Agarwal, Richard Brower, Timothy Raben +1
We give a new perspective on the Lorentzian OPE inversion formula of arXiv:1703.00278, building on arXiv:2302.06469. We introduce an ``auxiliary'' fourpoint function that can be re…
The Ising Model on
Richard C. Brower, Evan K. Owen
We define a 2-dimensional Ising model on a triangulated sphere, , designed to approach the exact conformal field theory (CFT) in the continuum limit. Surprisingly, the…
Stealth dark matter spectrum using LapH and Irreps
Richard C. Brower, Christopher Culver, Kimmy K. Cushman +17
We present non-perturbative lattice calculations of the low-lying meson and baryon spectrum of the SU(4) gauge theory with fundamental fermion constituents. This theory is one inst…
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…
The Operator Product Expansion for Radial Lattice Quantization of 3D Theory
Venkitesh Ayyar, Richard C. Brower, George T. Fleming +4
At its critical point, the three-dimensional lattice Ising model is described by a conformal field theory (CFT), the 3d Ising CFT. Instead of carrying out simulations on Euclidean…
Multigrid Algorithms for Domain-Wall Fermions
Saul D. Cohen, R. C. Brower, M. A. Clark +1
We describe an adaptive multigrid algorithm for solving inverses of the domain-wall fermion operator. Our multigrid algorithm uses an adaptive projection of near-null vectors of th…
