A scale Hamiltonian framework for multiscale systems: A Hamilton–Jacobi approach with application to glass-forming liquids

Abstract We develop a comprehensive scale Hamiltonian formalism for multiscale systems by recasting the renormalization group (RG) flow in a Hamiltonian framework and then reformulating it in terms of Hamilton–Jacobi...

Irreversible scale dynamics: Contact geometry and the arrow of renormalization

In the post “From Time to Scale Dynamics” we treated scale evolution as perfectly conservative: a Hamiltonian $H_{\text{scale}}$ moved through symplectic phase‑space $(g_i,p_i)$ just like a planet through ordinary space....

Canonical transformations and scheme independence

Recap. In the post “From Time to Scale Dynamics” we traded the ordinary notion of time for the log‑scale $\tau = \ln(\mu/\mu_0)$ and promoted the Hamiltonian itself to the role of...

Beyond the linear β: Higher-order scale dynamics — Revised

This post builds on “From Time to Scale Dynamics”, “Canonical Transformations & Scheme Independence”, and “Irreversible Scale Dynamics”. There we treated the renormalisation‑group (RG) β‑functions as the sole engine of...
