Brief introductions
Use tight binding model to get the surface states of slab systems or edge states of nanowire systems or just bulk bands. Especially usefull for topological novel systems, including topological insulator, Dirac semimetal, Weyl semimetal, nodal line systems, nodal chain systems, triple point systems and unknown topological systems.
With given tight binding model well written in the format of wannier90_hr.dat in Wannier90,
-
There are several examples in the examples folder, including Bi2Se3, WTe2, IrF4. The user guide is in the doc folder. Please read the user guide first.
-
Identify topological class by calculating the Wilson loop (Wannier charge center)
-
Get surface state spectrum (ARPES spectrum and STM QPI spectrum).
-
Identify Weyl points and nodal-line structure.
