Entropy Cost of ‘Erasure’ in Physically Irreversible Processes

open access: yesMathematics
A restricted form of Landauer’s principle, independent of computational considerations, is shown to hold for thermal systems by reference to the joint entropy associated with conjugate observables.

Holographic Dark Information Energy

open access: yesEntropy, 2011
Landauer’s principle and the Holographic principle are used to derive the holographic information energy contribution to the Universe. Information energy density has increased with star formation until sufficient to start accelerating the expansion of ...

Quantum Informational Dark Energy: Dark energy from forgetting

open access: yes, 2007
We suggest that dark energy has a quantum informational origin. Landauer's principle associated with the erasure of quantum information at a cosmic horizon implies the non-zero vacuum energy having effective negative pressure.

Information Equation of State

open access: yes, 2008
Landauer's principle is applied to information in the universe. Once stars began forming, the increasing proportion of matter at high stellar temperatures compensated for the expanding universe to provide a near constant information energy density.

A note on the Landauer principle in quantum statistical mechanics [PDF]

open access: yes, 2014
The Landauer principle asserts that the energy cost of erasure of one bit of information by the action of a thermal reservoir in equilibrium at temperature T is never less than $kTlog 2$.

Irreversibility beyond Landauer’s principle: is it possible to perform erasure using the quantum homogenizer?

open access: yesNew Journal of Physics, 2022
Erasure is fundamental for information processing. It is also key in connecting information theory and thermodynamics, as it is a logically irreversible task.

A non-equilibrium quantum Landauer principle [PDF]

open access: yes, 2015
Using the operational framework of completely positive, trace preserving operations and thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system.

Thermodynamics as a Consequence of Information Conservation [PDF]

open access: yesQuantum, 2019
Thermodynamics and information have intricate interrelations. Often thermodynamics is considered to be the logical premise to justify that $\textit{information is physical}$ - through Landauer's principle -, thereby also linking information and ...

Validity of Landauer's principle in the quantum regime

open access: yes, 2010
We demonstrate the validity of Landauer's erasure principle in the strong coupling quantum regime by treating the system-reservoir interaction in a consistent way. We show that the initial coupling to the reservoir modifies both energy and entropy of the

Towards a dynamical approach to the calculation of the figure of merit of thermoelectric nanoscale devices

open access: yes, 2012
Research on thermoelectrical energy conversion, the reuse of waste heat produced by some mechanical or chemical processes to generate electricity, has recently gained some momentum.
