Higher-Nuclearity Group 14 Metalloid Clusters: [Sn9{Sn(NRR′)}6]

Synthesis and Structural Characterization of Metalloid Al and Ga Clusters

Modular Nuclearity and Localization

Within the algebraic setting of quantum field theory, a condition is given which implies that the intersection of algebras generated by field operators localized in wedge–shaped regions of two–dimensional Minkowski space is non–trivial; in particular, there exist compactly localized operators in such theories which can be interpreted as local observables. The condition is based on spectral (nuc...

Chapter 14 Renormalization Group Theory

In this chapter, we discuss the renormalization-group (RG) approach to quantum field theory. As we will see, renormalization group theory is not only a very powerful technique for studying strongly-interacting problems, but also gives a beautiful conceptual framework for understanding many-body physics in general. The latter comes about because in practice we are often interested in determining...

A novel 2-D coordination polymer constructed from high-nuclearity waist drum-like pure Ho48 clusters.

A novel 2-D coordination polymer constructed from high nuclearity nanosized Ho48 clusters was synthesised and structurally characterized using single-crystal X-ray analysis. The Ho48 cluster core with a charming waist drum-like structure was templated by CO3(2-) ions, and bridged by Ho-N bonds to get a 2-D coordination polymer.

New high-nuclearity manganese clusters containing mixed chelating ligands: syntheses, crystal structures and magnetochemical characterization.

Two polynuclear mixed-valence manganese clusters, [Mn(13)] and [Mn(16)], containing mixed chelating ligands were synthesized and structurally characterized. The alternating current (AC) susceptibilities of both complexes reveal nonzero frequency-dependent out-of-phase (χ(M)'') signals.
