Abstract

Laser-driven generation of coherent radiation in bulk solids extending up to the extreme ultraviolet part of the spectrum [1] has recently open up completely new possibilities for study of electronic phenomena which lie beyond the scope of standard condensed phase physics spectroscopies. I will present how previous [2] and new tools of attosecond metrology [3][4] can now allow us to gain detailed insight into the fundamental microscopic processes responsible for the EUV emission in solids. We will show that this emission is in reality a macroscopic probe of nanoscale intraband coherent electric currents [5] the frequency of which is extending into multi-Petahertz range. On the basis of these findings, I will try to persuade you that we are now entering the realm of coherent electronics. A regime in which electronic circuitry can be conceived on the atomic level and where electronic properties of materials can be accessed [5] and controlled on attosecond time scales.
