Revisiting the $J_1$-$J_2$ Heisenberg Model on a Triangular Lattice: Quasi-Degenerate Ground States and Phase Competition

We provide the data underlying our publication, including static and dynamical correlation functions for both the ordered and the putative quantum spin liquid phases of the J1–J2 triangular-lattice Heisenberg antiferromagnet, as well as the MATLAB plotting scripts used in this study. All provided .mat files can be readily converted for use in Python, Julia, and other common programming languages.
