Ladyman et al (2007) proposed a model of the implementation of logical operations by physical processes in order to clarify the exact statement of Landauer’s Principle, and then offered a new proof of the latter based on the construction of a thermodynamic cycle, arguing that if Landauer’s Principle were false it would be possible to harness a machine that violated it to produce a violation of ...

I will discuss several distinct reasons for why present DFT calculations of transport, which combine ground-state DFT and the Landauer formula, might be highly inaccurate. (1) Even within the standard approach, common approximate functionals do not include a derivative discontinuity or correct for self-interaction. This can both misalign levels and broaden resonance peaks when a molecule is wea...

We propose that the Hawking radiation energy and entropy flow rates from a black hole can be viewed as a one-dimensional (1D), nonequilibrium Landauer transport process. Support for this viewpoint comes from previous calculations invoking conformal symmetry in the near-horizon region, which give radiation rates that are identical to those of a single 1D quantum channel connected to a thermal re...
