IHM is an … WebMele Hubbard model, respectively. This is realized by three Hamiltonians, H^ IH, H^IHZ and H^IHB, respectively. Conceptually, the Z2 broken Hamiltonian H^IHB has the most robust topology at the price of introducing a non-zero quantized spin current. The dimerized ionic Hubbard model H^ IH does not feature a strict topological

WebHubbard model have been investigated for this purpose, like the extended Hubbard model [1], the ionic Hubbard model in one and two dimensions [2–6], the two-band Hubbard model [7] and the bilayer Hubbard model [8–15]. The latter has been especially important in relation to the bilayer high-T c cuprates [16, 17]. Web23 okt. 2024 · The Hubbard model is based on the tight-binding approximation from solid-state physics, which describes particles moving in a periodic potential, typically referred to as a lattice. For real materials, each lattice site might correspond with an ionic core, and the particles would be the valence electrons of these ions.
