http://www.maplesoft.com/applications/view.aspx?SID=4865&ref=Feed
A package to manipulate and plot atomic orbitals and spherical harmonics. Hydrogenic and Slater-type orbitals are supported, as are arbitrary radial functions. Quantum mechanical integrals are included that act on these orbitals: 2-centre overlap integrals and 4-electron atomic integrals, including coulomb and exchange integrals.
Help pages and an example worksheet are included.
This is an update of a version of the orbitals package that was published in 2003.<img src="/view.aspx?si=4865/Orbitals_29.jpg" alt="Orbitals Package" align="left"/>A package to manipulate and plot atomic orbitals and spherical harmonics.

http://www.maplesoft.com/applications/view.aspx?SID=4812&ref=Feed
PX is a Maple package designed to implement non-commutative multiplication and commutation of quantum operators. In particular it is designed to deal with systems with several degree of freedom satisfying the commutation relations of operators and their conjugate momenta; i.e., operators such as p[x] and x, or alternatively their associated annihilation and creation operators.<img src="/view.aspx?si=4812//applications/images/app_image_blank_lg.jpg" alt="PX: A package for multiplication and commutation of quantum operators" align="left"/>PX is a Maple package designed to implement non-commutative multiplication and commutation of quantum operators.

http://www.maplesoft.com/applications/view.aspx?SID=1765&ref=Feed
A photon is postulated to be a wavetrain having a coherence length equal to one wavelength. The wavepulse is analyzed for a unified flux distribution, in its own inertial frame, based on the symmetric addition to the Poynting-Heaviside energy vector S of a gravitational cross product, as an alternative to that first proposed by Heaviside. From the mutual restoring force of the cross products a relativistic medium emerges, wherein there is no string, presenting an alternative to string/M-theory.
Maple 10 is used to analyze the symmetric three dimensional electric, magnetic, and gravitational flux distribution of the quantum on a similar basis to static charged rest mass electron-proton flux distributions in their own inertial frame. Eddington's detection of the deflection of light by the sun, and Tolman's detection of a gravitational component to electromagnetic radiation, previously attributed to spacetime curvature, are re-interpreted. The quantum's spacecurve flux distribution is shown in pair production to gain a spin moment, an added degree of freedom, through the interaction with the field of a nuclei, enabling the spherical expansion of the quantum into the electron and positron flux configurations.

http://www.maplesoft.com/applications/view.aspx?SID=4260&ref=Feed
The new ScientificConstants package in Maple 8 provides the values, symbols, uncertainty and units of over 13,000 physical constants. Never again do you have to search the internet or grab a reference book to look up such values. This extensive package gives you access to the basic chemical properties of any element or isotope from the Periodic Table. Also available are 70 physical constants, such as Planck's constant, the Newtonian constant of gravitation, magnetic flux quantum, and speed of light in a vacuum. If a specific physical constant that you need is not included, simply add the constants you commonly use to Maple's database. This flexible package also allows you to modify properties or change the system associated with a constant. The ScientificConstants package in conjunction with the comprehensive Units package introduced in Maple 7 together provide valuable tools for scientists and engineers.<img src="/view.aspx?si=4260//applications/images/app_image_blank_lg.jpg" alt="The ScientificConstants Package" align="left"/>The new ScientificConstants package in Maple 8 provides the values, symbols, uncertainty and units of over 13,000 physical constants.

Solution of the Schroedinger equation by the Numerov-method for any given one-dimensional eigenvalue problem is shown here. The central idea is to fix the eigenvalue and solve the differential equation. If the resulting function is not an eigenfunction, the deviation serves as a guide how to change the eigenvalue.
