# Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines

@article{Kish2015CriticalRO, title={Critical remarks on Landauer's principle of erasure-dissipation: Including notes on Maxwell demons and Szilard engines}, author={Laszlo B. Kish and Sunil P. Khatri and Claes G{\"o}ran Granqvist and Janusz M. Smulko}, journal={2015 International Conference on Noise and Fluctuations (ICNF)}, year={2015}, pages={1-4} }

We briefly address Landauer's Principle and some related issues in thermal demons. We show that an error-free Turing computer works in the zero-entropy limit, which proves Landauer's derivation incorrect. To have a physical logic gate, memory or information-engine, a few essential components necessary for the operation of these devices are often neglected, such as various aspects of control, damping and the fluctuation-dissipation theorem. We also point out that bit erasure is typically not…

### Zero and negative energy dissipation at information-theoretic erasure

- Computer ScienceArXiv
- 2015

A new non-volatile, charge-based memory scheme wherein the erasure can be associated with even negative energy dissipation; this implies that the memory’s environment is cooled during information erasure and contradicts Landauer's principle of erasure dissipation.

### Hidden Dissipation and Irreversibility in Maxwell’s Demon

- PhysicsEntropy
- 2022

The transport fluxes of mass, momentum, and energy involved in the demon's operation are analyzed and show that they imply "hidden" external work and dissipation, indicating one mechanism by which macroscopic irreversibility may emerge from microscopic dynamics.

### Response to “Comment on ‘Zero and negative energy dissipation at information-theoretic erasure”’

- Computer ScienceArXiv
- 2016

It is proved that statistical information-theoretic quantities, such as information entropy, cannot generally be interrelated with the lower limit of energy dissipation during information erasure, and that information entropy does not convert to thermodynamic entropy and to the related energy Dissipation.
