Wormhole calculus, replicas, and entropies

open access: yesJournal of High Energy Physics, 2020
We investigate contributions of spacetime wormholes, describing baby universe emission and absorption, to calculations of entropies and correlation functions, for example those based on the replica method. We find that the rules of the “wormhole calculus”

QCD vacuum replicas are metastable [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the meson spectra in the excited QCD vacua, denominated replicas. We find all mesons have real masses, with no tachyons, thus showing the QCD replicas are indeed metastable.
