Quantitative determination of the orbital-selective Mott transition and quantum entanglement in the orbital-selective Mott phase
We examine the orbital-selective Mott transition in the non-hybridized two-band Hubbard model using the dynamical mean-field theory. We find that the orbital-selective Mott transition could be quantitatively depicted by the local two-qubit fidelity. Furthermore, within the orbital-selective Mott phase, the combined characteristics of the two orbitals lead to the presence …
