GTFermiSurface
GTFermiSurface[Hamiltonian,Fermi energy,list of bands,ndel, kbasis,clusterdata,BZPath]
calculates the Fermi surface corresponding to a Hamiltonian and Fermi energy if the Fermi surface contains parts from list of bands. The electronic structure is calculated in a cube at ndel points per spatial dimension. kbasis is the basis of the reciprocal lattice. clusterdata contains the data for the lattice construction. The path used in electronic structure calculations can be provided by BZPath.
