The Entropic Damping Force (EDF)

Key Points

Investigate the entropic damping force's role in enforcing entropic stabilization in dimensional measurement equilibrium.
Derived expressions rigorously from a non-geometrical toy model of open system renormalization group flow.
Examined the coupling of a visible sector coordinate with a hidden conformal bath.
Analyzed results in conjunction with current precision tests, including optical clocks and muon g − 2.
Developed a theoretical framework consistent with the observed null results from precision tests.
Identified viable parameters for the entropic damping force that align with experimental data.

Abstract

ENTROPIA is a minimal, two parameter phenomenological benchmark for possible scaledependence in effective fundamental couplings, such as the gravitational constant G or the finestructure constant α. It takes the double exponential form λ(ℓ) = λ01 + δexp(−exp(βℓ)).This paper derives this form rigorously from a non geometrical toy model of open system RGflow, in which a visible sector collective coordinate is weakly coupled to a large hidden conformal bath. The Entropic Damping Force (EDF) acts as the dynamical mechanism enforcingentropic stabilization in Dimensional Measurement Equilibrium (DME). Viable parameters arefully consistent with current null results from precision tests (optical clocks, muon g − 2, LHCRun 3)
