LaTeX Template for Research Papers

Below is a copy‑pasteable LaTeX template based on RevTeX 4.2. It has an appendix‑only table of contents and correct PDF bookmarks. To help navigate in super long appendices, the pagenumber in appendices are designed to be clickable: clicking it will bring you back to the table of contents. A new environment eqsplit is introduced, which is a shorthand for equation + split that gives you multiline equations with a single numbering. All warnings are fixed.
