Symmetry-initialized quantum Gibbs sampling: a non-Abelian asymmetry cascade

Soo-Jong Rey

For a quantum Gibbs sampler whose mixing bottleneck is a weakly broken symmetry, I show that the correct initialization is determined by representation theory. I first prove a gene…

The Infraparticle Edge

Soo-Jong Rey

The paper derives the charged‑particle spectral edge in quantum electrodynamics by treating soft photons as a quantum instrument, showing how infrared effects and unresolved photon…

-Form Gauge Dynamics and Digital Quantum Simulation -- Flux and Cosmological Constant Neutralization

Soo-Jong Rey

I develop a Hamiltonian framework for -form gauge fields on arbitrary oriented cell complexes in arbitrary dimensions. Gauge qudits are defined by -cells, cha…

Horizon-Restricted Leading Soft QED as Open Quantum System

Soo-Jong Rey

I formulate black-hole-horizon-induced decoherence of charged branch codes as the leading-soft QED restricted to an exterior algebra, formulated as an open quantum system. The fixe…

Infrared Safety from ZX-Diagrams: A Categorical Proof of Soft-QED as Open Quantum System

Soo-Jong Rey

The discard ZX-calculus, a diagrammatic language for mixed-state quantum mechanics, is used to give a nonperturbative, categorical proof of the Bloch-Nordsieck cancellation of infr…

Soft QED as Open Quantum System: Infrared Cancellation and Soft-Shell Coarse Graining

Soo-Jong Rey

I formulate unresolved soft-photon sector of QED as open quantum system. Resolved charged particles and hard photons form the system, unresolved soft photons form the environment,…
