Strong-field ionization (SFI) is a key process for accessing real-time quantum dynamics of electrons on the attosecond timescale. The theoretical foundation of SFI was pioneered in the 1960s, and ...
A new framework shows how lost information in quantum systems gives rise to macroscopic entropy and the arrow of time Water ripples (Courtesy: Shutterstock/Ken Schulze) In the macroscopic world, we ...
THE support given by Profs. Hill and Grünbaum in their interesting communication is very encouraging. The problem before us—before these two authors as well as before myself—is the clarification of ...
