bloch function meaning in Hindi

Examples

1. The Bloch function can be expanded in the following manner:
2. Bloch functions can be represented as a Fourier series
3. However it is not easy to calculate directly either Bloch functions or Wannier functions.
4. These Bloch functions can be pictured as periodic repetition of atomic orbitals, repeated at intervals corresponding to the lattice spacing.
5. Of course, if we have exact Wannier functions, the exact Bloch functions can be derived using the inverse Fourier transform.
