Motivated by this fact, we study the chemical pressure effect on the single-layered La2CuO4 and HgBa2CuO4 starting from the two-orbital Hubbard model deduced from a first-principles calculation. It is shown that the chemical pressure effects induced by La-site substitution in La2CuO4 or Hg-site substitution in HgBa2CuO4 are not expected to be effective for raising Tc.}, pages = {34--37}, publisher = {Elsevier B.V.}, title = {Theoretical study of the chemical pressure effect on Tc in the cuprate superconductors}, volume = {58}, year = {2014} }
