Absztrakt:
Highly charged ions (HCIs) provide a unique platform for precision studies of 
nuclear structure and fundamental physics in extreme electromagnetic fields. 
Over the past decade, our work has demonstrated that spectroscopy of 
quasi-hydrogenic highly charged ions can provide a powerful new approach for 
measuring nuclear charge radii and probing nuclear structure with high 
sensitivity and reduced systematic uncertainties. The method combines 
high-accuracy ab initio atomic-structure calculations with precision 
spectroscopy of Na-like ions produced and trapped in electron beam ion traps 
(EBITs). The strong enhancement of nuclear-size effects in heavy HCIs 
substantially relaxes the required spectroscopic resolution while enabling 
access to very heavy and short-lived nuclei.
I will present recent developments in EUV and x-ray spectroscopy of highly 
charged ions, including measurements of isotope shifts, absolute nuclear 
charge radii, and cross-element constraints in heavy nuclei. These studies 
have direct relevance to tests of quantum electrodynamics (QED), nuclear 
deformation, electric-dipole-moment-sensitive nuclei, atomic parity 
non-conservation, and future nuclear-clock systems such as 229Th.
The seminar will also discuss emerging opportunities at the interface of EBIT 
spectroscopy and coherent EUV science. In particular, the combination of 
next-generation EBIT platforms with coherent extreme-ultraviolet and 
high-harmonic-generation (HHG) sources opens new possibilities for absolute 
EUV calibration, coherent spectroscopy of highly charged ions, pump-probe 
studies in extreme electromagnetic fields, and future precision measurements 
beyond the limits of conventional grating spectroscopy. These developments 
suggest a new scientific direction connecting highly charged ions, coherent 
EUV spectroscopy, and frontier studies of nuclear structure and fundamental 
physics.
