Precision measurements of β-decay observables offer the possibility to search for deviations
from the Standard Model. A possible discovery of such deviations requires accompanying …

We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses.
Using 30 fs pulses, we observe periodic enhancements of the excitation yield in the intensity …

Multiple high precision β-decay measurements are being carried out these days on various
nuclei, in search of beyond the Standard Model (SM) signatures. These measurements …

The nonrelativistic effective field theory (NRET) is widely used in dark matter direct detection
and charged-lepton flavor violation studies through μ→ e conversion. However, existing …

We report an exploratory study of the O (α) structure-dependent electromagnetic radiative
corrections to unique first-forbidden nuclear beta decays. We show that the insertion of …

We present a joint experimental-theoretical study on the effect of the carrier-envelope phase
(CEP) of a few-cycle pulse on the atomic excitation process. We focus on the excitation rates …

We report precision measurements of the Ne 20–Ne 22 isotope shift for several transitions,
as well as state-of-the-art, ab initio field-shift calculations. Our results are combined with …

A multipole decomposition of a cross section is a useful tool to simplify the analysis of
reactions due to their symmetry properties. By using a new approach to decompose …

We visualize frustrated tunneling ionization (FTI) using the correlation function analysis
outlined in our preceding works [I. Ivanov and KT Kim, J. Phys. B 55, 055001 (2022) 0953 …

Precise measurements of nuclear beta decays provide a unique insight into the Standard
Model due to their connection to the electroweak interaction. These decays help constrain …
