WebProof: First, we show that the Hilbert-Schmidt tensor product H= V bWcannot be a Hilbert-space tensor product. For simplicity, suppose that V;Ware separable, in the sense of having countable Hilbert-space bases. [2] Choice of such bases allows an identi cation of W with the continuous linear Hilbert space dual V of V. WebThe operators E i j := ψi ψ j form a basis of B(H), the linear maps on H, which is orthonormal once that space is endowed with the Hilbert-Schmidt inner product. A straightforward computation using Prop. 17 shows that E i j are eigenvectors of L and the eigenvalues LE i j = λi j E i j satisfy λi j = λ ji , Re λi j ≤ 0 and λi j = 0 ...

WebHilbert–Schmidt integral operators are both continuous (and hence bounded) and compact (as with all Hilbert–Schmidt operators). The concept of a Hilbert–Schmidt operator may be extended to any locally compact Hausdorff spaces. Specifically, let X be a locally compact Hausdorff space equipped with a positive Borel measure.

WebJul 27, 2024 · Given a fermionic Hamiltonian in a matrix form, we can write it as a sum over Kronecker products of Pauli matrices using the Hilbert-Schmidt inner product. However if the same Hamiltonian is given in a operator form, we can use the Jordan-Wigner transformation to write it as a sum over Kronecker products of Pauli operators.
