This question provides a discussion on how to determine whether a square matrix is invertible. That is, does the square matrix have an inverse so that if we matrix multiply the matrix with its inverse we get the square identity matrix. Inverses of matrices are used a lot in the area of ...

H.C. is Hermitian conjugate. The subindex, e.g., “1” is the combined index of k-point and band. P is the generalized scattering-rate matrix considering e-ph, e-i and e-e scattering processes, computed from the corresponding scattering matrix elements and energies of electrons and ...
If we take a look at the difference quotient here, we notice that it is symmetrical, which is to say, the samples used to calculate the second derivative lie symmetrically around the point at which we seek to calculate the derivative. This means we can create a Hermitian matrix describ...
