Local orbital occupation and energy levels of Co in Na_{x} CoO_{2} : A soft x-ray absorption study
Author(s): H.-J. Lin, Y. Y. Chin, Z. Hu, G. J. Shu, F. C. Chou, H. Ohta, K. Yoshimura, S. Hébert, A. Maignan, A. Tanaka, L. H. Tjeng, and C. T. Chen<br/>We present a combined experimental and theoretical investigation on the orbital occupation and local symmetry of Co in Na_{x} CoO_{2} . We have carried out polarization dependent Co−L_{2,3} soft x-ray absorption spectroscopy measurements. By comparing the spectra with the results of configuration-...<br/><img src="http://prola.aps.org/graphics/free2read30x30.gif" width="30" height="30" alt="Free to Read"/><br/>[Phys. Rev.

Direct evidence of the multidimensionality of the free-energy landscapes of proteins revealed by mechanical probes
Author(s): Zu Thur Yew, Michael Schlierf, Matthias Rief, and Emanuele Paci<br/>The study of mechanical unfolding, through the combined efforts of atomic force microscopy and simulation, is yielding fresh insights into the free-energy landscapes of proteins. Thus far, experiments have been mostly analyzed with one-dimensional models of the free-energy landscape. We show that as...<br/><img src="http://prola.aps.org/graphics/free2read30x30.gif" width="30" height="30" alt="Free to Read"/><br/>[Phys. Rev. E 81, 031923] Published Tue Mar 30, 2010

Predicting the Effective Temperature of a Glass
Author(s): Nicoletta Gnan, Claudio Maggi, Thomas B. Schrøder, and Jeppe C. Dyre<br/>We explain the findings by Di Leonardo et al. [Phys. Rev. Lett. 84, 6054 (2000)] that the effective temperature of a Lennard-Jones glass depends only on the final density in the volume and/or temperature jump that produces the glass. This is not only a property of the Lennard-Jones liquid, but a fe...<br/><img src="http://prola.aps.org/graphics/free2read30x30.gif" width="30" height="30" alt="Free to Read"/><br/>[Phys. Rev.
