Strong-coupling analysis of scanning tunneling spectra in Bi2Sr2Ca2CuBerthod1, Fasano2, Maggio-Aprile3 et al. 2013Phys. Rev. B

“…44,[74][75][76] The hopping t 3 (second neighbor along the Cu-Cu direction) is negative like t 1 , as expected from symmetry considerations. Likewise, the diagonal hoppings t 2 and t 5 are both positive, or the latter is almost zero (we consider the small negative values of order 1 meV as insignificant).…”

ARPES-parameterized Hubbard approach to d-wave cuprate superconductors

“…x p , the experimental data of T c from M. Hashimoto, et al [6] allow the determination of the correlated hopping parameters t 3 for each doping concentration, whose values are presented in Table 1.…”

“…In particular, such dispersion relationship around the Fermi energy for Bi 2 Sr 2-x La x CuO 6+δ (BSLCO), with different chemical compositions x, has been measured by extrapolating the peaks of momentum distribution curves up to the Fermi energy (E F ) even when the spectral weight is suppressed in going towards E F due to the presence of an energy gap or pseudogap [6]. Notice that in BSLCO, as the La concentration x increases, the hole concentration p decreases, as determined by the room-temperature Hall coefficient [11].…”

“…This approach could be used to calculate the hole doping p for each x, instead of utilizing the temperature-dependent Hall coefficient and its comparison with other cuprates, as a guide to estimate p [11]. together with the experimental T c and Hall-effect estimated hole doping p [6].…”

“…Even in this single-band generalized Hubbard model there are several parameters that should be determined. In this article, we find out single-and correlatedelectron-hopping parameters for Bi 2 Sr 2-x La x CuO 6+δ (BSLCO), within the mean-field approximation, from the angleresolved photoemission spectroscopy (ARPES) experimental data [6]. We have previously applied this method to La 2 x Sr x CuO 4 systems finding a good agreement between the theoretical results and experimental data of the critical temperature (T c ) as well as the electronic specific heat [7].…”
