– Time dependence and boundary conditions for leads¶
3.2.1. Adding time-dependence¶
|
Add a time-dependent voltage to a lead. |
3.2.2. Boundary conditions¶
Boundary conditions for systems with leads attached; used with the solvers in tkwant.onebody.solver.
|
Boundary conditions consisting of N lead unit cells. |
|
Absorbing boundary conditions consisting of N lead unit cells. |
|
Make an absorbing boundary from a user provided-absorbing potential. |
|
Routine to find automatically a boundary condition such that the reflection amplitude \(r\) for a lead stays below a given value. |
3.2.3. Analyse lead reflection¶
|
Calculate the reflection amplitude \(r\) for a lead with imaginary absorbing potential. |
|
Analyze the the reflection for a lead. |
|
Analyze the the reflection for a lead for the special case of a monomial absorbing potential. |
