Event DetailsEvent Dates: Thursday, December 3, 2015 - 2:00pmSeminar Location: JILA X325Speaker Name(s): Janko NautaSpeaker Affiliation(s): Max Planck Institute for Nuclear Physics Quantum Dynamics and Control Seminar Type/SubjectScientific Seminar Type: JILA Public SeminarEvent Details & Abstract: Highly charged ions (HCI) are atomic systems with a few tightly bound electrons. They exhibit much more pronounced quantum electrodynamic effects than neutrals and singly charged particles, thus allowing for accurate tests of fundamental theories. Recently, ultra-narrow transitions have been predicted which might be suitable for the next generation optical clocks. In Heidelberg, we use electron beam ion traps to study HCI. I will present different experiments which have been performed recently in our group, and ultimately discuss a new project where we want to use an XUV frequency comb to study HCI with ultra-high precision. This will open up an exciting and un-explored field of high-precision spectrocopy in the extreme ultraviolette regime on these ions.
