Pilot wave approach to the NRT nonlinear Schrödinger equation

Pennini, F.; Plastino, A.R.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 403 (2014) C, pp. 195-205

We investigate the main features of a pilot wave representation of the nonlinear Schrödinger equation recently advanced by Nobre, Rego-Monteiro, and Tsallis (NRT) on the basis of Tsallis q-thermo-statistical formalism. The present approach sheds new light upon the NRT equation. In particular,...

Quasi-stationary states of the NRT nonlinear Schrödinger equation

Toranzo, I.V.; Plastino, A.R.; Dehesa, J.S.; Plastino, A. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 18, pp. 3945-3951

With regards to the nonlinear Schrödinger equation recently advanced by Nobre, Rego-Monteiro, and Tsallis (NRT), based on Tsallis q-thermo-statistical formalism, we investigate the existence and properties of its quasi-stationary solutions, which have the time and space dependences...

Investigation of nucleation and grain growth in 2-dimensional systems by using generalized Monte Carlo simulations

Cetinel, Hakan; Kayacan, Ozhan; Ozaydin, Demet - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 18, pp. 4121-4126

In this study, nucleation and grain growth was studied by using 2-dimensional generalized Monte Carlo simulations and experiments. As an attempt to improve the JMAK model, we proposed a new differential equation to be able to model nucleation and growth phenomena using nonextensive...

Non-extensive treatment of surface nucleation on glass particles

Nascimento, Marcio Luis Ferreira - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 23, pp. 6077-6083

derived from Tsallis thermostatistics and another based on the Johnson–Mehl–Avrami–Yerofeyev–Kolmogorov (JMAYK) theory. For … crystallization mode from three dimensional to one dimensional as JMAYK predicts, and this is advantageous. Furthermore, Tsallis … thermostatistics contains the Austin–Rickett model as a special and limiting case study for this system. A generalized Avrami plot is …

Nonextensive treatment of nucleation and growth in a thin layer

Cetinel, Hakan; Kayacan, Ozhan - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 263-271

In this study, a generalized method based upon nonextensive statistics is presented for nucleation and growth processes in a thin layer between two interfaces. It is shown that the presented mathematical model, which uses an index called the entropic index that measures the nonextensivity of the...

The influence of nonextensivity on orientational ordering in liquid crystal systems with variable molecular shape

Kayacan, Ozhan - In: Physica A: Statistical Mechanics and its Applications 354 (2005) C, pp. 344-354

A generalized model taking into account the photoisomerization influence on the nematic ordering is presented. This generalized theory is used to investigate the effect of the nonextensivity on the concentration dependence of the long-range order parameter. The q-dependent variation of the...
