Note

SuperScreen uses semantic versioning, with version numbers specified as MAJOR.MINOR.PATCH. In particular, note that:

Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.
Version 1.0.0 defines the public API.

Version 0.8.0¶

Release date: 2022-12-15

Removed dependency on optimesh, as it is not longer open source.
- superscreen.Device.make_mesh() and superscreen.Polygon.make_mesh() now take an integer argument, smooth, which specifies the number of Laplacian mesh smoothing iterations to perform.

Release date: 2022-08-29

Added support for GPU-acceleration in superscreen.solve(), with JAX as an optional dependency (#75).
Added superscreen.TransportDevice, a subclass of superscreen.Device on which one can define source/drain terminals for current biasing (#78).
Updated superscreen.Solution.field_at_position() to use the 2D Biot-Savart directly, via superscreen.sources.biot_savart_2d() (#78).
Updated superscreen.fluxoid.find_fluxoid_solution() to use the mutual inductance matrix to solve for fluxoid states, which is much more efficient than the previous least-squares method, especially for multiple holes (#78).

Release date: 2022-07-02

Fixed an off-by-one error in the \(k\)-space coordinates used to calculate the field from a Pearl vortex in superscreen.sources.pearl_vortex() (#74).

Release date: 2022-05-20.

Note: On GitHub, this version was accidentally tagged as v0.6.6 rather than v0.6.0 (see here.)

Release date: 2022-04-13

Added \(\vec{\nabla}\Lambda(x, y)\) term and clarified documentation about the model in the context of inhomogeneous films (#72).

Release date: 2022-03-15

Release date: 2022-01-27

Use __slots__ for Layers, Polygons, and Parameters (#57).
Add affine transformations for Polygon and Device (#59, #60).
Allow Parameters to return scalar or vector quantities (# 61).
Allow explicitly setting num_cpus in solve_many() (#62).
Add SheetCurrentField source and move mesh generation into its own module to enable Polygon.make_mesh() (#65).
Use scipy.linalg.lu_solve() in superscreen.solve() instead of numpy.linalg.inv() (#67).
