Landauer's principle in multipartite open quantum system dynamics [PDF]

, 2015
We investigate the link between information and thermodynamics embodied by Landauer's principle in the open dynamics of a multipartite quantum system.

Does a computer have an arrow of time? [PDF]

, 2007
In [Sch05a], it is argued that Boltzmann's intuition, that the psychological arrow of time is necessarily aligned with the thermodynamic arrow, is correct.

A Dynamic Dark Information Energy Consistent with Planck Data

Entropy, 2014
The 2013 cosmology results from the European Space Agency Planck spacecraft provide new limits to the dark energy equation of state parameter. Here we show that Holographic Dark Information Energy (HDIE), a dynamic dark energy model, achieves an optimal ...

Going Round in Circles: Landauer vs. Norton on the Thermodynamics of Computation

Entropy, 2014
There seems to be a consensus among physicists that there is a connection between information processing and thermodynamics. In particular, Landauer’s Principle (LP) is widely assumed as part of the foundation of information theoretic/computational ...

The Demon in a Vacuum Tube

Entropy, 2013
In the present paper, several issues concerning the second law of thermodynamics, Maxwell’s demon and Landauer’s principle are dealt with. I argue that if the demon and the system on which it operates without dissipation of external energy are made of ...

Limits of Landauer’s principle and of the second law of thermodynamics

Entropie
Since 1857, the second law of thermodynamics has faced the challenge of Maxwell’s imagined demon. The widely accepted response to this challenge suggests that the demon requires a bit of information to work, and according to Landauer’s principle ...

Upper Limit on the Thermodynamic Information Content of an Action Potential

Frontiers in Computational Neuroscience, 2020
In computational neuroscience, spiking neurons are often analyzed as computing devices that register bits of information, with each action potential carrying at most one bit of Shannon entropy.

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

, 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 $kTlog 2$.

Full counting statistics approach to the quantum non-equilibrium Landauer bound

New Journal of Physics, 2017
We develop the full counting statistics of dissipated heat to explore the relation with Landauer’s principle. Combining the two-time measurement protocol for the reconstruction of the statistics of heat with the minimal set of assumptions for Landauer’s ...
