applications
plain-language theorem explainer
Catalog of four application domains for the Landauer bound once it is tied to the RS recognition timescale τ₀: near-thermodynamic computing, DNA computing limits, neural energy efficiency, and quantum energy budgets. Cited by anyone mapping INFO-004 outputs to engineering or biophysics use cases. The body is a static string list, not a proved claim.
Claim. The documented application areas of the Landauer minimum erasure energy $E_{\min}=k_B T\ln 2$, when derived from the RS timescale $\tau_0$, are: (i) computers designed to approach the thermodynamic limit, (ii) DNA computing optimization, (iii) neural computational efficiency, and (iv) quantum-computer energy budgets.
background
Module INFO-004 derives Landauer's principle from Recognition Science rather than taking it as an external thermodynamic axiom. Classically, erasing one bit raises entropy by $k_B\ln 2$ and dissipates at least $Q=k_B T\ln 2$ as heat. In RS the same bound is read off the recognition timescale $\tau_0$ together with the J-cost of a recognize-then-forget cycle: $\tau_0$ fixes the rate at which that cost is paid.
Sibling definitions in the module supply the concrete constants: Boltzmann factor $k_B$, room temperature, the positive Landauer energy, its room-temperature value, $\tau_0$ in seconds, the linked quantum energy scale, minimum erasure power, and the identification of erasure J-cost with the thermodynamic expression. Parallel applications lists exist for channel capacity and the Zeno effect; they play the same catalog role in neighboring information and quantum modules.
proof idea
No proof. The declaration is a def whose body is a four-element literal List String. There are no tactics, no lemmas, and no reduction steps.
why it matters
Gives the engineering and biophysics landing zone for the INFO-004 derivation (Landauer bound from $\tau_0$ and J-cost). The module doc flags patent potential for ultra-low-power architectures that approach the Landauer limit with RS-inspired designs, and a paper target on thermodynamics of information from RS. Downstream references include the matching applications catalogs in ChannelCapacity and ZenoEffect, plus incidental uses from gravity and foundation modules that pull the shared applications pattern. It does not itself close a forcing-chain step (T0–T8); it records where the bound is meant to be used once proved.
