Superconducting 0-Pi impurity quantum phase transition
M. Žonda et al present results for phase diagrams, level occupation, induced local superconducting gap, Josephson current, and energy of the Andreev bound states with the precision surpassing any (semi)analytical approaches employed thus far.
Ultrafast spintronics: Give it a whirl
Measurements of laser-induced magnetization dynamics suggest that spin currents can be generated on ultrafast timescales. Now it is shown that such currents may be capable of exerting ultrafast spin-transfer torques.
