Irreversible phase transitions induced by an oscillatory input
Alfredo C. Lopez, Gustavo P. Saracco, Ezequiel V. Albano
A novel kind of irreversible phase transitions (IPT's) driven by an oscillatory input parameter is studied by means of computer simulations. Second order IPT's showing scale invari…

Enhancement of Antiferromagnetic Correlations Induced by Nonmagnetic Impurities: Origin and Predictions for NMR Experiments
Markus Laukamp, George Balster Martins, Claudio J. Gazza +5
Spin models that have been proposed to describe dimerized chains, ladders, two dimensional antiferromagnets, and other compounds are here studied when some spins are replaced by sp…
