Dendrimers are highly branched nanoparticles with complex three-dimensional structures. They are composed of multiple internal repeating units covalently linked to the nucleus (called generations) and usually possess multiple functional groups on the exterior. Monodispersity, nanosize, bioavailability, solubility...
lattice sites have a net positive charge (red) because of a higher contribution from the nucleus, whereas the regions around lattice sites have a net negative charge (blue) indicating a higher contribution from the electrons. It is non-trivial to separate the contributions of the nucleus and ...
In addition, the ratio of positive charges on the nucleus to the number of orbital electrons is increased. Thus the effective nuclear charge is increased and the electrons are pulled in. A positive ion is therefore smaller than the corresponding atom and the more electrons removed (that is, ...
The critical charge of a nucleusPopov, V S
In particular, one could not explain the existence of the weak interaction that only acts at very short distances, and is responsible for radioactivity within the nucleus of an atom. Why is it such an important particle? This Higgs field played an absolutely decisive role in the first moments...

The nucleus 208Pb is of particular interest because it exhibits a simple structure and is experimentally accessible. However, computing such a heavy nucleus has been out of reach for ab initio theory. By combining advances in quantum many-body methods, statistical tools and emulator technology, we...
