The present paper investigates the Faraday effect and absorption and luminescence spectra of single-crystal TbF3 measured at 90 K and 300 K. The optical-quality single-phase TbF3 crystals (structural type β-YF3) were grown by the Bridgman technique. Faraday rotation angles were measured at remagnetization along the [100] crystallographic axis. Low temperature optical measurements were carried out along the [100] axis. “Quasi-doublet” sublevels with energy at 0 cm-1, 65 cm-1 and 190 cm-1, and also a singlet sublevel with energy at 114 cm-1 located in the ground 7F6 multiplet were determined from the …

The big bang and inflation are experimentally confirmed by multitudes of astronomical observations, yet theoretical tension still exists upon a very important question: why is there something rather than nothing? In other words, why are there unequal amounts of matter and antimatter? Why did a supposedly initially symmetric state not annihilate perfectly?
The breaking of this symmetry has allowed for all of material existence--also known as baryogenesis, the prevalence of matter over antimatter--and yields the theoretical possibility of direct detection by observation of baryon number violating mechanisms, which have previously never been observed.
One such plausible mechanism can be found …
