Orbital resolved wannier plot
WebWannier orbital is defined as 𝑤𝑹𝒓= 1 σ −𝑖 𝑹𝜓 𝒓 a. For any lattice vector 𝑹′, 𝑤 𝑹𝒓+𝑹′ =𝑤𝑹𝒓, so that 𝑤𝑹𝒓=𝑤𝒓−𝑹 b. Bloch function can be written as a superposition of the Wannier c. Orthogonal to each other 𝑤𝑹𝑤𝑹′ =𝛿𝑹,𝑹′ WebStep 0: Find the orbitals and energy range to be used in the Wannier Function Hamiltonian.¶ Before we can construct the Hamiltonian in the basis of the Wannier functions, we need to determine which orbitals to include in the construction. We need to include the orbitals with energies around the Fermi energy (\(E_F\)). Since we are interested ...

Physical … WebA Wannier orbital is an atomic orbital, because it is (or at least should be) localized around an atom. Sometimes they are also localized between two atoms, e.g. an sp2 hybrid orbital …
WebFeb 1, 2024 · Using the real-space Wannier Hamiltonian, we calculate the band structure of all the equivalent k-paths and illustrate them in a single plot [Fig. 3 (a)]. In the ideal case, the band structures from these equivalent high symmetry k-paths should be exactly the same. However, the Wannierization procedure has no symmetry constraint and the ...
