WebThe matrix elements of r over Bloch orbitals are ill defined. Because of this, the problem of macroscopic electric polarization remained unsolved until the early 1990s. Breakthrough (1992 –): “Modern theory of polarization”. Magnetic analogue (2005 –) “Modern theory of orbital magnetization”..... Web21 uur geleden · Preferential selection of a given enantiomer over its chiral counterpart has become increasingly relevant in the advent of the next era of medical drug design. In parallel, cavity quantum electrodynamics has grown into a solid framework to control energy transfer and chemical reactivity, the latter requiring strong coupling.
