kwant.builder.SelfEnergyLead

class kwant.builder.SelfEnergyLead(selfenergy_func, interface, parameters)

Bases: Lead

A general lead defined by its self energy.

Parameters:

• selfenergy_func (function) – Has the same signature as selfenergy (without the self parameter) and returns the self energy matrix for the interface sites.

• interface (sequence of Site instances)

• parameters (sequence of strings) – The parameters on which the lead depends.

Methods

finalized()

Trivial finalization: the object is returned itself.
