Package used for obtaining the results in 1807.05702.
This undergraduate research project studies 3D conformal field theories (CFTs) with a parity symmetry. Specifically, we used this package initially for studying theories with two relevant scalars, one being parity even (\epsilon) and the other being parity odd (\sigma), giving theories with the same operator structure as the 3D Ising model. After this, we lowered the gap assumptions on the next lowest-lying parity odd scalar to make the operator relevant, and used this to isolate the minimal supersymmetric Ising model.
In both cases, we applied the usual crossing symmetry constraints on the four point functions associated with a given candidate CFT to rule out the space of possible scaling dimensions for the theories. Further, we performed c-minimization and ran scans over the OPE coefficients.
We expand on the earlier work of Kos, Poland, Simmons-Duffin, and Vichi in 1603.04436. We make make use of mixed correlator constraints, as well as a "theta scan" method to examine the possible 3-pt coefficient ratios of a given theory.
This project makes use of T. Ohstuki's
cboot module for sage to build the relevant conformal blocks, and D. Simmons-Duffin's
sdpb to employ the semidefinite programming for determining the feasibility of a given set of correlators satisfying the bootstrap constraints.
