Eigenvalues of kronecker product

1. Bilinearity and associativity: The Kronecker product is a special case of the tensor product, so it is bilinear and associative: where A, B and C are matrices, 0 is a zero matrix, and k is a scalar. 2. Non-commutative: In general, A ⊗ B and B ⊗ A are different matrices. However, A ⊗ B and B ⊗ A are permutation equivalent, meaning that there exist permutation matrices P and Q such that If A and B are square matrices, then A ⊗ B and B ⊗ A are even permutation similar, meaning that … WebSep 7, 2016 · In order to obtain the eigenvalues of this Hamiltonian we simply diagonalize the matrix where stands for the 2 × 2 identity matrix. Note that the application of the Kronecker-product rule is considerably more straightforward than the explicit calculation of the matrix elements of the Hamiltonian in the tensor-product spin basis set [ 7 ].
