An Automated Generation of Bootstrap Equations for Numerical Study of Critical Phenomena

Abstract

In this thesis, we introduce new tools for the conformal bootstrap, autoboot and qboot. Each tool solves a different step in the whole computational stack, and combined with an existing efficient tool SDPB which solves semidefinite programming (SDP), our tools make it easier to study conformal field theories with more complicated global symmetries and with more general spectra. In the introduction, we review how the conformal bootstrap method gives rich information about the theory at the fixed point of renormalization group, or in other words, the critical phenomena such as the Ising model at criticality. The following three sections focus on the theories behind the implementation of autoboot and qboot, and the explicit implementation, freely available at https://github.com/selpoG/autoboot/ and https://github.com/selpoG/qboot/, is discussed in section 5. We also have two applications in the last section, the Ising model and the O(2) vector model in three dimensions, each of them has close relationship with a physical system in the real world.
