amazing! the Ejs community is bigger than i thought http://www.uco.es/hbarra/index.php/fc/appletsfc http://www.uco.es/hbarra José Ignacio Fernández Palop  Universidad de Córdoba (http://www.uco.es/hbarra/Blog/Elisabet.jpg) i use Google chrome which translate Spanish to English easily. the following is the translation of the page http://www.uco.es/hbarra/index.php/fc/appletsfc THE ORIGINS OF QUANTUM PHYSICS The main physical phenomena that led to the establishment of quantum theory were the blackbody thermal radiation, the photoelectric effect, Compton effect, etc.. In this section there are applications that intend to study each of these physical phenomena. Thermal blackbody radiation The photoelectric effect Photoelectric effect Compton effect The dispersion Thompson Young's experiment Diffraction through a slit SCHRÖDINGER EQUATION The Schrödinger equation of quantum mechanics is what Newton's equation of classical mechanics. In this section there are some applications that try to help understand the wave nature of particles analyzing various phenomena of the wave theory, such as: the phase velocity and group Fourier transform, etc. You can also see the solution of the Schrödinger equation of the simplest case, which is that of a free particle. Dispersion of a particle system Phase velocity and group Fourier Integral type Wave function in the representation of time Fourier transform of a Gaussian wave packet Temporal evolution of a free particle Motion of a particle in a potential gradient SIMPLE ONEDIMENSIONAL PROBLEMS. SQUARE POTENTIAL. Dimensional potential are increasingly used to analyze the motion of particles in large application systems such as semiconductors. Today it has gotten even confine particles in one dimension but negligible dimension in the socalled quantum dots. In this section there are applications that allow the analysis of stationary and nonstationary solutions of several onedimensional square potential. Classical motion of a particle in square potential Stationary solutions of the potential step Motion of a wave packet in the potential step Stationary solutions of the potential barrier Motion of a wave packet in a potential barrier Transmission coefficient of the potential barrier Motion of a wave packet through cracks variables Movement of a wave packetthrough slits variable Stationary states of the infinite well potential Motion of a wave packet in an infinite well potential Stationary states of finite potential well DIMENSIONAL SYSTEMS. THE HARMONIC OSCILLATOR. The first applications of this section are devoted to analyzing how the solution of the Schrödinger equation for different timeindependent onedimensional potential. One of the most useful methods for solving onedimensional square potential is the propagation matrix. By some applications can analyze the properties of this matrix. Finally, one of the most important potential is the harmonic oscillator because in many cases the motion of a system as it moves away slightly from equilibrium can be described by this potential. The latest applications to analyze the steady and unsteady solutions of the harmonic oscillator in quantum mechanics. Solving the equation of timeindependent Schrödinger Solution of the Schrödinger equation for timeindependent bound states Propagation matrix Propagation matrix for the energies of bound states of a finite well Propagation matrix for a periodic potential Bound states of simple harmonic oscillator Motion of a wave packet in the harmonic oscillator potential Classical limit of the harmonic oscillator file THE CLASSICAL LIMIT. THE WKB APPROXIMATION. The analysis of the classical limit and how quantum mechanics contains the classical as a limit case, yields approximate solutions of the Schrödinger equation time independent from the classical solution and this is the WKB approximation. By the following applications can analyze how the WKB approximate solution and how it can be used to calculate transmission coefficients and energies of bound states. The principle of least action Airy functions Transmission coefficient for a triangular potential WKB approximation to calculate the energies of bound states The transmission coefficient using the WKB approximation The WKB approximation when the energy is greater than the potential Time evolution of a variable frequency oscillator ANGULAR MOMENTUM IN QUANTUM MECHANICS. One of the most important mechanical quantities is the angular momentum as it has an associated conservation law. The following applications to analyze the eigenfunctions of angular momentum in quantum mechanics, which are harmonics eesféricos. The last application to analyze the fact that rotations do not commute among themselves. Spherical harmonics Court of spherical harmonics with the plane z Rotations THE TWOBODY PROBLEM IN QUANTUM MECHANICS. THE HYDROGEN ATOM. One of the few systems of interest to support an analytical solution in quantum mechanics is the hydrogen atom. The following applications to analyze the stationary states (orbitals) of the hydrogen atom, and the behavior of a hydrogen atom in a magnetic field and electric field. Orbitals of the hydrogen atom Orbitals of the hydrogen atom in three dimensions Radial probability density of the first states of the hydrogen atom The hydrogen atom in a magnetic field  Paramagnetism The hydrogen atom in an electric field  Stark Effect SPIN. Spin is an intrinsic angular momentum with elementary particles. The following applications help We understand the properties of spin. Rotations in spin space Title: Re: José Ignacio Fernández Palop  Universidad de Córdoba Post by: ahmedelshfie on December 30, 2010, 04:44:13 pm I see, is who design the Photoelectric http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2002.0
Good job what they done in Universidad de Córdoba, they done many good applets. Ejs community always upgrade by users in all world, is the best tool.
