Flux period, spin gap, and pairing in the one-dimensional t-J-J'-model
Alexander Seidel, Dung-Hai Lee
Using the factorization of the wavefunction in the t-J-J'-model at small exchange couplings, we demonstrate the connection between the existence of a spin gap and an hc/2e flux per…

Lightly doped dimerized spin chain in the one-dimensional t-J-J' model
Alexander Seidel, Patrick A. Lee
We study the one-dimensional t-J-J'-model in the limit of small hole doping and small , . Special emphasis is put on the regime where a spin gap is…

Giant phonon anomalies in the pseudo-gap phase of TiOCl
P. Lemmens, K. Y. Choi, G. Caimi +4
We report infrared and Raman spectroscopy results of the spin-1/2 quantum magnet TiOCl. Giant anomalies are found in the temperature dependence of the phonon spectrum, which hint t…
