This chapter provides an introduction to Unimodular Gravity both at the classical and quantum level, discussing the r\^ole it might play in the partial solution of the Cosmological Constant problem. The main objective of this work is to serve as a conceptual introduction to Unimodular gravity without disregarding computational detail. In that sense, techniques used at the research level are presented and applied in detail.

  1. Dark energy genesis: modeling dissipative effects in primordial cosmology

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Ohmic dissipation into quantum-gravity defects in unimodular cosmology generates a small positive asymptotic cosmological constant from an initially vanishing dark-energy density.

  2. G\"{o}del-type universes in unimodular gravity

    gr-qc 2025-06 reject novelty 5.0 of 10

    Gödel-type universes in unimodular gravity are claimed to reproduce the causal structure of general relativity, but the paper's field equations do not admit the solutions it presents.
