Recent experiments suggest that the superconducting order parameter of Sr$_2$RuO$_4$ has two components. A two-component multiple degrees freedom in state can result low-energy collective modes or formation domain walls -- a possibility would explain number experimental observations including smallness time reversal symmetry breaking signal at T$_\mathrm{c}$ and telegraph noise critical current...

Visualizing large data by the SOM and GTM methods – what are we obtaining? Anna Bartkowiak University of Wrocław, Institute of Computer Science, Przesmyckiego 20, Wrocław 51–151, PL Abstract We consider the visualization of multivariate data yielded by the SOM and the GTM methods. Special emphasis is put on the position of outliers and extreme points. When evaluating four data sets, it is found...

We present scanning tunneling microscopy (STM) images of single-layer graphene crystals examined under ultrahigh vacuum conditions. The samples, with lateral dimensions on the micrometer scale, were prepared on a silicon dioxide surface by direct exfoliation of crystalline graphite. The single-layer films were identified by using Raman spectroscopy. Topographic images of single-layer samples di...
