Clock Fields and Logarithmic Decay of Dark Energy

Year: 2024

Type: article

Abstract: We investigate the physical measurability of the infrared instability of a de Sitter phase in the formalism recently proposed. We find that the logarithmic decay of the effective cosmological constant is only measurable if an additional clock field is introduced.
