tkwant.leads.GenericAbsorbingBoundary¶

class tkwant.leads.GenericAbsorbingBoundary(num_cells, imaginary_potential, num_buffer_cells=0)[source]¶

Make an absorbing boundary from a user provided-absorbing potential.

Parameters

imaginary_potential (callable) – User-provided absorbing potential.
num_cells (int) – The number of lead unit cells over which the absorbing potential increases.
num_buffer_cells (int, optional) – If provided, adds this many lead cells to the start of the boundary conditions with no absorbing potential applied.
