Quantum Lenoir Engine with a Single Particle System in a One Dimensional Infinite Potential Well

open access: yesPositron, 2019
Lenoir engine based on the quantum system has been studied theoretically to increase the thermal efficiency of the ideal gas. The quantum system used is a single particle (as a working fluid instead of gas in a piston tube) in a one-dimensional infinite ...

Nonlinear Schrödinger equations near an infinite well potential [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2013
The paper deals with standing wave solutions of the dimensionless nonlinear Schrödinger equation \label{eq:abs1} iΦ_t(x,t) = -Δ_xΦ+V_\la(x)Φ+ f(x,Φ), \quad x\in\R^N,\ t\in\R,\tag{$NLS_\la$} where the potential $V_\la:\R^N\to\R$ is close to an infinite well potential $V_\infty:\R^N\to\R$, i. e. $V_\infty=\infty$ on an exterior domain $\R^N\setminus\Om$,

Analytical Model of an I-core Coil for Nondestructive Evaluation of a Conducting Cylinder below an Infinite Plane Conductor

open access: yesMeasurement Science Review, 2021
An analytical model for eddy current testing of an I-core coil located above a two-layer conductive material is presented. The upper layer is an infinite plane conductor, and the bottom layer is a conductive cylinder.

Structure Theory for Extended Kepler-Coulomb 3D Classical Superintegrable Systems [PDF]

open access: yes, 2012
The classical Kepler-Coulomb system in 3 dimensions is well known to be 2nd order superintegrable, with a symmetry algebra that closes polynomially under Poisson brackets. This polynomial closure is typical for 2nd order superintegrable systems in 2D and

Non-standard and Numerov finite difference schemes for finite difference time domain method to solve one-dimensional Schrödinger equation

open access: yesJournal of Physics: Theories and Applications, 2018
The purpose of  this paper is to show some improvements of the finite-difference time domain (FDTD) method using Numerov and non-standard finite difference (NSFD) schemes for solving the one-dimensional Schrödinger equation.

Evaluation of an imidazolium-based ionic liquid as a separation solvent for binary mixtures based on limiting activity coefficient data

open access: yesSouth African Journal of Chemical Engineering, 2020
The separation of volatile organic solvents (herewith, solutes) were tested in an imidazolium-based ionic liquid (1,3-dimethylimidazolium dimethylphosphate), [MMIM] [DMP] as a solvent at four different temperatures, T = (313 .15 to 343.15) K and at ...

Dimensionality and geometry effects on a quantum carnot engine efficiency

open access: yesRevista de Ciencias Tecnológicas, 2019
We calculate the efficiency of a quantum Carnot cycle for a particle confined in two different infinite potential wells, a cylindrical potential well of variable radius and a two-dimensional square potential well with a periodicity in one of it sides. We
