The isolated systems are useful mostly for analysis of band structure, spectrum, density of states, and any kind of basic properties. Kwant 2 should allow defining various interfaces between systems with higher symmetry and lower symmetry. The main feature of Kwant 1, a scattering region with 1D leads is the most commonly used and the simplest example of such an interface. |
