Attoclocks, or attosecond clocks, are instruments that can measure time intervals on the attosecond scale by measuring the time it takes for electrons to tunnel out of atoms. The attosecond procedure was first introduced ...
Physicists at Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China developed a simple concept that could significantly improve magnetic-based data processing. Using ultrashort electric pulses in ...
