Rare-earth ion doped crystals for hybrid quantum technologies are an area of growing interest in the solid-state physics community. We have earlier theoreticall
Based on radioactive phenomena (weak force), Georges Lemaître conceives, as soon as 1927, the primeval universe as a “unique super-dense quantum”, whose
CONTEXT The spin of a particle is physically manifest in multiple phenomena. For quantum mechanics (QM), spin is an intrinsic property of a point particle, but
In 1916, F.S. Macaulay developed specific localization techniques for dealing with “unmixed polynomial ideals” in commutative algebra, transforming them into
