Anomalous critical behavior near the quantum critical point of a hole-doped La2CuO4
Y. Chen, Wei Bao, J. E. Lorenzo +4
The Landau-Ginzburg-Wilson paradigm for critical phenomena is spectacularly successful whenever the critical temperature is finite and all fluctuation modes, with characteristic en…

Charge ordering in oxides : a conundrum solved by resonant diffraction
Y. Joly, S. Grenier, J. E. Lorenzo
We show that in mixed-valence 3d transition metal oxides undergoing a structural transition, the low temperature phase results from an effective ordering of the charge. This arrang…

Comment on "Two Dimensional Ordering and Fluctuations in alpha'-NaV2O5"
S. Ravy, J. E. Lorenzo
We claim that the analysis presented by Gaulin et al. (Phys. Rev. Lett. 84, 3446 (2000)) does not prove the two-dimensional character of the transition in NaV2O5 nor the charge ord…
