Abstract: We report on the epitaxial growth and surface structure of infinite-layer cuprate ${\mathrm{Sr}}_{1\ensuremath{-}x}{\mathrm{Nd}}_{x}{\mathrm{CuO}}_{2}$ films on ${\mathrm{SrTiO}}_{3}$(001) substrates by combining ozone-assisted molecular beam epitaxy and in situ scanning tunneling microscopy. Careful substrate temperature and flux control… read more here.

Abstract: Three types (three-band, two-band, and one-band) of effective Hamiltonians for ${\mathrm{HgBa}}_{2}{\mathrm{CuO}}_{4}$ and three-band effective Hamiltonian for ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$ are derived by improving the constrained-$GW$ approximation combined with the self-interaction correction ($\mathrm{c}GW\ensuremath{-}\text{SIC}$) formulated by Hirayama et al.… read more here.
