Attosecond electron dynamics

Ursula Keller
Zurich, Switzerland


With the recent progress in few-optical-cycle femtosecond and attosecond pulse generation with full electric field control we can measure attosecond electron dynamics. Based on different theoretical approximations and experimental techniques we have made significant progress in our understanding of attosecond ionization dynamics from atoms, molecules and surfaces. In addition terahertz spectroscopy can be scaled towards petahertz with electric-field-driven electron dynamics in condensed matter targets such as diamond, GaAs and Ti.


Ursula Keller has been a tenured professor of physics at ETH Zurich since 1993 (, and also a director of the Swiss multi-institute NCCR MUST program in ultrafast science since 2010 ( She received the Ph.D. from Stanford University in 1989 and the Physics "Diplom" from ETH in 1984. She was a Member of Technical Staff (MTS) at AT&T Bell Laboratories from 1989 to 1993, a “Visiting Miller Professor” at UC Berkeley 2006 and a visiting professor at the Lund Institute of Technologies 2001. She has been a co-founder and board member for TimeBandwidth Products (acquired by JDSU in 2014) and for a venture capital funded telecom company GigaTera (acquired by Time-Bandwidth in 2003). She was a member of the research council of the Swiss National Science Foundation from 2014-2018. She is the founding president of the ETH Women Professors Forum.
