Symmetries of 2+1D Non-Hermitian Chiral Majorana Surface States in Topological Superconductor

This thesis investigates the emergent symmetries and classifications of non-Hermitian chiral Majorana surface states in topological superconductors, with a focus on 2+1- dimensional (2+1D) boundary modes. Using tools from conformal field theory (CFT), the research explores how 1+1D chiral Majorana edge theories can be used to analyse 2+1D surfaces with complex energy spectra, where steady-state configurations replace traditional ground states. The study develops a framework for deriving equations of motion, operator product expansions, and correlation functions on 2+1D boundaries.
