Pair correlations in doped Hubbard ladders

Year: 2015

Type: article

Abstract: There has been some controversy regarding the dominant correlations in weakly doped Hubbard ladders. Analytical approaches find them to be superconducting but numerical approaches have thus far pointed otherwise. Using cutting-edge DMRG techniques on extremely large system sizes this controversy is now resolved to show that superconducting correlations indeed dominate.
