Information theory link between MaxEnt and a key thermodynamic relation

Curado, E.M.F.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 386 (2007) 1, pp. 155-166

We focus attention on the particular thermodynamic relation dU=TdS+δW. Using information theory concepts we show that, for a reversible process in which intensive variables change, microscopic considerations related to this thermodynamic relation make the informational contents of,...

Computation of energy exchanges by combining information theory and a key thermodynamic relation: Physical applications

Curado, E.M.F.; Nobre, F.D.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 5, pp. 970-980

By considering a simple thermodynamic system, in thermal equilibrium at a temperature T and in the presence of an external parameter A, we focus our attention on the particular thermodynamic (macroscopic) relation dU=TdS+δW. Using standard axioms from information theory and the fact that the...

Generating statistical distributions without maximizing the entropy

Plastino, A.; Curado, E.M.F. - In: Physica A: Statistical Mechanics and its Applications 365 (2006) 1, pp. 24-27

We show here how to use pieces of thermodynamics’ first law to generate probability distributions for generalized …

Nonextensive normalized treatment of Clausius equation

Martínez, S.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 345 (2005) 3, pp. 493-505

We revisit the first law of thermodynamics for nonextensive statistics by recourse to the optimal Lagrange multipliers … (OLM) formalism. We show firstly that information theory allows one to obtain thermodynamics' first law in a general …

The role of constraints in Tsallis' nonextensive treatment revisited

Ferri, G.L.; Martínez, S.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 347 (2005) C, pp. 205-220

We revisit the nonextensive treatment advanced by Tsallis, et al. (Physica A 261 (1998) 534) in order to perform a rather exhaustive study of its properties and compare them with the earlier formalism devised by Curado and Tsallis (J. Phys. A 24 (1991) L69). Some interesting features are in this...
