Deviation density matrix
Web• An alternative approach to working with the density matrix is to express the matrix (deviation matrix) as a linear combination of matrix basis functions (B) σˆ(t)=c n B n n ∑ • Requirements: - one basis matrix for each element (4 for single spin density matrix) - basis matrices are orthogonal (but not necessarily normalized) WebOff-diagonal elements at equilibrium • must satisfy time dependent Schrodinger Eq. H = (i2 /h) / t = E ; in limit of H = H 0 • Solution is: n = n exp(i2 /h)E n t • But, the members of the ensemble do not have a common
