Exact Zero Temperature Correlation Functions for Two-Leg Hubbard Ladders and Carbon Nanotubes
Robert Konik, Andreas W. W. Ludwig
Motivated by recent work of Lin, Balents, and Fisher (cond-mat/9801285), we compute correlation functions at zero temperature for weakly coupled two-leg Hubbard ladders and (N,N) a…

Two-Leg Ladders and Carbon Nanotubes: Exact Properties at Finite Doping
R. Konik, F. Lesage, A. W. W. Ludwig +1
Recently Lin, Balents, and Fisher have demonstrated that two-leg Hubbard ladders and armchair carbon nanotubes renormalize onto the integrable SO(8) Gross-Neveu model. We exploit t…
