Dimerization-induced enhancement of the spin gap in the quarter-filled two-leg rectangular ladder
Y. Yan, S. Mazumdar, S. Ramasesha
We report density-matrix renormalization group calculations of spin gaps in the quarter-filled correlated two-leg rectangular ladder with bond-dimerization along the legs of the la…

Density matrix renormalization group study of conjugated polymers with transverse pi-conjugation
Y. Yan, S. Mazumdar
We report accurate numerical studies of excited state orderings in long hypothetical pi-conjugated oligomers in which the hydrogen atoms of trans-polyacetylene are replaced with co…
