Schrödinger Lab 2.20 release notes and screen shots

Schrödinger Lab 2.20 has been submitted to the Mac App Store.  If all goes well, it should be approved in approx 9 days time. 

First things first, here's the new icon!  The Schrödinger Labrador is now modeled by 'Tegan'.

I've made numerous tweaks to the interface, so here are some screenshots from the new-look palettes. 

The above screenshot shows off the new 2D 'Angular x Radial' basis functions, which are eigenfunctions of the 2D isotropic harmonic oscillator which are separable in polar coordinates.

The 2D Quantum double Well

An attempt at a double slit simulation.  I admit, this example could be improved.  I need to play around with this a little more.

The Morse Oscillator.

The finite square well in periodic boundary conditions.

Here are the release notes:

Big update!

Schrödinger Lab can now switch between displaying eigenfunctions or basis-functions. It's now possible to show how the wavefunction is decomposed in terms of the basis-functions and to display each basis-function.

In the 2D palettes, Schrödinger Lab can now use basis-functions Χ_m,n(r,theta)=R_m,n(r)T_m(theta) which are separable in polar coordinates, where R_m,n(r) are constructed from Laguerre polynomials and T_m(theta)=e^(I'm theta) with theta=atan2(y,x) is the angular function.

Many improvements to the interface, including:

i) Mouse rotations in the 2D palettes now work better, and the rotation is now always performed about the axis origin.

ii) More elegant window-resizing behavior.

iii) Introducing 'Tegan', our new model for the Schrödinger Labrador, who also features in the new icon.

Eigenfunction color palettes used to indicate phase now have uniform brightness.

Fixed a bug where the number of basis-functions in the 1D palettes was capped at 64.
