Gapped hamiltonian
WebMay 18, 2024 · A Hermitian gapped Hamiltonian H (k) of any two-band model in momentum-space is given by the following generic Hamiltonian (1) H (k) = h x (k) σ x + h y (k) σ y + h z (k) σ z where the components of the vector h → = (h x (k), h y (k), h z (k)) are k-dependent 3-dimensional real-valued functions and σ x, σ y and σ z are the well-known ... Webgapped Hamiltonian is constant in time in the thermodynamic limit when the Hamiltonian is subjected to a perturbation in general time dependent that preserves the locality of the Hamiltonian. A possible change of the index in a certain time scale is only a finite size effect, this is the content of eq. (27).

WebJul 4, 2024 · Also, it is known (Fact 2) that the groundstate of any 1D gapped Hamiltonian can be well approximated by an MPS (Hastings 2007). So let me define an exact MPS groundstate, like the AKLT state to the AKLT model, to be an MPS that is not an approximation to the groundstate of the 1D gapped Hamiltonian. Hence, any arbitrary …
