How do cold ions slide?
Trieste, Italy (SPX) May 28, 2013
Things not always run smoothly. It may happen, actually, that when an object slides on another, the advancement may occur through a 'stop and go' series in the characteristic manner which scientists call "stick-slip", a pervasive phenomenon at every scale, from earthquakes to daily-life objects, up to the "nano" dimension. Davide Mandelli, Andrea Vanossi and Erio Tosatti of the International School for Advanced Studies (SISSA) of Trieste have studied the conditions in which at the nanoscopic level ... read more
