Thermodynamics of Knowing
In the paper's words
This paper re-frames the physical basis of knowledge as a non-equilibrium thermodynamic process. We reject equilibrium models and identify the “Epistemic Cut” as a dissipative phase transition in a driven open quantum system, specifically the Dicke Model. Through mean-field simulations, we demonstrate that a stable, information-bearing state (a symbol) is a non-equilibrium steady state (NESS) that requires a continuous energy flux to maintain against environmental decoherence.

Numbers it reports
Section 5.0 analyzes the thermodynamic efficiency of this transition, quantifying the Entropy Production Rate required to maintain the “knowing” state.
from 1.7 RoadmapThis quadratic advantage in the signal-to-noise ratio means the emergent consensus state is inherently robust against thermal fluctuations (Rey, 2025).
from 2.6The true cost is the Entropy Production Rate (EPR) , which quantifies the rate at which the system dissipates heat into the environment to maintain its low-entropy, ordered state (Still et al., 2012).
from 3.5As the pump strength $\lambda$ is increased to cross the critical threshold $\lambda_c \approx 1.59$, the system undergoes a dissipative phase transition.
from 4.2 Emergence of theThis elegant mapping, where the logical state is the macroscopic dynamical attractor, is a hallmark of an efficient and well-designed epistemic engine (Baltag & Smets, 2010).
from 4.5 Logic Mapping: From NESSAs shown in our simulation, this transition is continuous but sharp; the photon number rises from zero to a macroscopic value ($n_{ss} \approx 0.01$ per particle, or $N n_{ss} \approx 10$ total photons) as $\lambda$ exceeds the critical threshold of 1.59.

How it is done
This approach eliminates the need for cryogenics and promises an exponential gain in efficiency, forming the architectural thesis of this work.
from 1.4 TheSection 3.0 will detail our methodological framework, formally defining the open Dicke Hamiltonian and the Lindblad master equation used to model the system.
from 1.7 RoadmapThe profound inefficiency of this approach mandates a complete rejection of the paradigm in favor of collective field interactions.
from 2.2 The Inadequacy ofWe define our order parameter as the steady-state photon number per particle, $n_{ss} = |\alpha_{ss}|^2 = \langle a^\dagger a \rangle_{ss} / N$.

Where the claim stops
We do not simulate finite-size quantum fluctuations, entanglement entropy, or specific solid-state implementations, though we propose a schematic for such a device.
from 1.6 Scope and LimitationsThe primary limitation is the translation from this idealized mean-field model to a specific, noisy experimental platform, which is left for future work.
from 1.6 Scope and LimitationsWhile this provides a mechanism for the emergence of classicality, it does not fully specify the architecture required for a system to process this emergent information as knowledge.
