Three-particle scattering amplitudes from a finite volume formalism
Raul A. Briceno, Zohreh Davoudi
We present a quantization condition for the spectrum of a system composed of three identical bosons in a finite volume with periodic boundary conditions. This condition gives a rel…
Constraints on the Universe as a Numerical Simulation
Silas R. Beane, Zohreh Davoudi, Martin J. Savage
Observable consequences of the hypothesis that the observed universe is a numerical simulation performed on a cubic space-time lattice or grid are explored. The simulation scenario…
Restoration of Rotational Symmetry in the Continuum Limit of Lattice Field Theories
Zohreh Davoudi, Martin J. Savage
We explore how rotational invariance is systematically recovered from calculations on hyper-cubic lattices through the use of smeared lattice operators that smoothly evolve into co…
Moving Multi-Channel Systems in a Finite Volume with Application to Proton-Proton Fusion
Raul A. Briceno, Zohreh Davoudi
The spectrum of a system with multiple channels composed of two hadrons with nonzero total momentum is determined in a finite cubic volume with periodic boundary conditions using e…
