Laser excitation of the 1s-hyperfine transition in muonic hydrogen
SciPost Physics, 2022 The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen ($\mu$p) with 1 ppm accuracy by means of pulsed laser spectroscopy to determine the two-photon-exchange contribution with $2\times10^{-4}

The inverted singlet–triplet gap: a vanishing myth?
Frontiers in Chemistry, 2023 Molecules with an inverted singlet–triplet gap (STG) between the first excited singlet and triplet states, for example, heptazine, have recently been reported and gained substantial attention since they violate the famous Hund’s rule.

Chinese Journal of Magnetic Resonance, 2020 The long-life nuclear spin singlet states (LLSs) have broad application prospects due to the unique nature of their long lifetime. Herein, in a solution of alanylglycylgcine (AGG), the nuclear spin singlet state of a two-spin system far from the chiral ...

Quenched scalar meson correlator with Domain Wall Fermions [PDF]
, 2002 We study the singlet and non-singlet scalar-meson masses using domain wall fermions and the quenched approximation. The singlet mass is found to be smaller than the non-singlet mass and indicates that the lowest singlet meson state could be lighter than ...

Understanding/unravelling carotenoid excited singlet states [PDF]
Journal of The Royal Society Interface, 2018 Carotenoids are essential light-harvesting pigments in natural photosynthesis. They absorb in the blue–green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and thus expand the wavelength range of light that is able to drive photosynthesis.
