Summary
This study generalizes the Landauer principle using Tsallis entropy, impacting information theory and physics. It explores consequences like modified information mass and gravitational field effects on information erasure.
Area of Science:
- Thermodynamics
- Information Theory
- Statistical Mechanics
Background:
- The Landauer principle sets a fundamental limit on energy dissipation during information erasure.
- This limit is intrinsically linked to the concept of entropy in physical systems.
- Current understanding primarily relies on standard Boltzmann-Gibbs statistical mechanics.
Purpose of the Study:
- To generalize the Landauer principle by incorporating Tsallis entropy.
- To explore the implications of this generalized principle on information physics.
- To investigate novel phenomena arising from non-extensive statistical mechanics in information processing.
Main Methods:
- Theoretical derivation of a generalized Landauer limit using Tsallis entropy.
- Analysis of the relationship between Tsallis parameters and energy dissipation.
- Extension of the principle to systems influenced by gravitational fields.
Main Results:
- A modified lower bound for energy dissipation in information erasure based on Tsallis entropy.
- A redefinition of the mass associated with one bit of information.
- The principle's applicability to systems in gravitational fields, including gravitational wave emission.
Conclusions:
- Tsallis entropy provides a broader framework for understanding information thermodynamics.
- The generalized Landauer principle has implications for information mass and gravitational interactions.
- This work opens new avenues for research at the intersection of information theory, gravity, and non-extensive statistical mechanics.

Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has expanded in a vacuum remains dispersed and never spontaneously reassembles. The unidirectional nature of these phenomena is the result of a thermodynamic state function called entropy (S). Entropy is the measure of the extent to which the energy is dispersed throughout a system, or in other words, it is proportional to the degree of disorder of a...

Entropy and the Second Law of Thermodynamics
2.7K
The second law of thermodynamics can be stated quantitatively using the concept of entropy. Entropy is the measure of disorder of the system.
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...

Second Law of Thermodynamics

In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, a significant conclusion regarding the relation between this property and spontaneity may be reached. In thermodynamic...

The Second Law of Thermodynamics

In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Scientists refer to the measure of randomness or disorder within a system as entropy. High entropy means high disorder and low energy. To better understand entropy, think of a student’s bedroom. If no energy or work were put into it, the room would quickly become messy. It would exist in a very disordered state, one of high entropy. Energy must be...

Third Law of Thermodynamics
18.2K
A pure, perfectly crystalline solid possessing no kinetic energy (that is, at a temperature of absolute zero, 0 K) may be described by a single microstate, as its purity, perfect crystallinity,and complete lack of motion means there is but one possible location for each identical atom or molecule comprising the crystal (W = 1). According to the Boltzmann equation, the entropy of this system is zero.

Standard Entropy Change for a Reaction

Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in standard entropy between the products and the reactants.
