On the origin of biquadratic exchange in spin 1 chains
Frederic Mila, Fu-Chun Zhang
One dimensional spin 1 systems may have a rich phase diagram including Haldane gap and dimerized phases if the usually very small biquadratic exchange becomes significant. We show…

Spin and Charge Texture around In-Plane Charge Centers in the CuO_2 planes
Stephan Haas, Fu-Chun Zhang, Frederic Mila +1
Recent experiments on La_2Cu_{1-x}Li_xO_4 show that although the doped holes remain localized near the substitutional Li impurities, magnetic order is rapidly suppressed. An examin…
