Embedding Space Approach to Lorentzian CFT Amplitudes and Causal Spherical Functions
Pulkit Agarwal, Richard C. Brower, Timothy G. Raben +1
Conformal Field Theory in a Minkowski setting is discussed in an embedding space approach, paying special attention to causality constraints for four-point amplitudes. The physics…
The Pomeron -- A Bootstrap Story
Chung-I Tan
In a contribution to the volume {\it A Passion for Physics}, a collection of essays in honor of Geoffrey Chew's sixtieth birthday, I wrote, together with A. Capella, Uday Sukhatme,…
Application of Lorentzian CFT Principal Series Representation to Near Forward Scattering
Pulkit Agarwal, Richard C. Brower, Timothy G. Raben +1
We present a discussion on recent progress in high energy diffraction from the perspective of AdS/CFT, through which a unified treatment for both perturbative and nonperturbative P…
Radial Lattice Quantization of 3D Field Theory
Richard C. Brower, George T. Fleming, Andrew D. Gasbarro +4
The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization o…
Lattice Setup for Quantum Field Theory in AdS
Richard C. Brower, Cameron V. Cogburn, A. Liam Fitzpatrick +2
Holographic Conformal Field Theories (CFTs) are usually studied in a limit where the gravity description is weakly coupled. By contrast, lattice quantum field theory can be used as…
Lattice Field Theory on Riemann Manifolds: Numerical Tests for the 2-d Ising CFT on
Richard C. Brower, Michael Cheng, George T. Fleming +4
We present a method for defining a lattice realization of the quantum field theory on a simplicial complex in order to enable numerical computation on a general Riemann manif…
