Motivated by the recent work of Mandal and Jarzynski on an autonomous Maxwell demon information engine, we have extended their model by introducing two different heat baths. The system (demon) is coupled to a memory register (tape) and a work source. The performance of the system depends on the interplay between the two sources along with the heat baths. We have found that the system can act as an engine, refrigerator or an eraser. Even the combination of any two is possible in some parameter… 

Second law, Landauer’s principle and autonomous information machine

Second law of thermodynamics can be apparently violated in systems whose dynamics depend on information acquired by measurement. However, when one considers measurement and erasure together with the

Second law for an autonomous information machine connected with multiple baths

In an Information machine system's dynamics gets affected by the attached information reservoir. Second law of thermodynamics can be apparently violated for this case. In this article we have derived

From a feedback-controlled demon to an information ratchet in a double quantum dot

We present a simple strategy for constructing an information ratchet or memory-tape model of Maxwell’s demon, from a feedback-controlled model. We illustrate our approach by converting the

Autonomous conversion of information to work in quantum dots

We consider an autonomous implementation of Maxwell's demon in a quantum dot architecture. As in the original thought experiment, only the second law of thermodynamics is seemingly violated when

Information ratchets exploiting spatially structured information reservoirs.

This work shows that the dimensionality of the reservoir has a significant impact on the performance and phase diagram of the demon and derives exact probabilities of recurrence in these systems, generalizing previously known results.

Efficiency at the maximum power of the power law dissipative Carnot-like heat engines with non-adiabatic dissipation

We study the efficiency at the maximum power of non-adiabatic dissipative (internally dissipative friction in finite time adiabatic processes) Carnot-like heat engines operating in finite time under

Use and Abuse of Entropy in Biology: A Case for Caliber

Suggestions for use of caliber, a metric similar to entropy but for time-dependent trajectories rather than static distributions, and propose the complementary notion of path information are suggested.



A Maxwell Demon Model Connecting Information and Thermodynamics

In the past decades several theoretical Maxwell's demon models have been proposed to exhibit effects such as refrigerating, doing work at the cost of information, and some experiments have been

Work and information processing in a solvable model of Maxwell’s demon

A minimal model of an autonomous Maxwell demon, a device that delivers work by rectifying thermal fluctuations while simultaneously writing information to a memory register, offers a simple paradigm for investigating the thermodynamics of information processing by small systems.

An autonomous and reversible Maxwell's demon

Building on a model introduced by Mandal and Jarzynski (Proc. Natl. Acad. Sci. U.S.A., 109 (2012) 11641), we present a simple version of an autonomous reversible Maxwell's demon. By changing the

Maxwell's refrigerator: an exactly solvable model.

We describe a simple and solvable model of a device that-like the "neat-fingered being" in Maxwell's famous thought experiment-transfers energy from a cold system to a hot system by rectifying

On the energetics of information exchange

We consider the thermodynamic properties of systems in contact with an information source and focus on the consequences of energetic cost associated with the exchange of information. To this end we

Unifying three perspectives on information processing in stochastic thermodynamics.

Stochastic thermodynamics is generalized to the presence of an information reservoir and it is shown that both the entropy production involving mutual information between system and controller and the one involving a Shannon entropy difference of an Information reservoir like a tape carry an extra term different from the usual current times affinity.

Experimental verification of Landauer’s principle linking information and thermodynamics

It is established that the mean dissipated heat saturates at the Landauer bound in the limit of long erasure cycles, demonstrating the intimate link between information theory and thermodynamics and highlighting the ultimate physical limit of irreversible computation.

Irreversibility and heat generation in the computing process

Two simple, but representative, models of bistable devices are subjected to a more detailed analysis of switching kinetics to yield the relationship between speed and energy dissipation, and to estimate the effects of errors induced by thermal fluctuations.

Thermodynamics from Information

Thermodynamics and information have intricate inter-relations. The justification of the fact that information is physical, is done by inter-linking information and thermodynamics – through Landauer’s

The thermodynamics of computation—a review

Computers may be thought of as engines for transforming free energy into waste heat and mathematical work. Existing electronic computers dissipate energy vastly in excess of the mean thermal
