This chapter describes the strong and weak interactions of beryllium to form covalent bonds
and beryllium bonds. We start from the challenging description of bonding in the beryllium …

Risk assessment is the key process for environmental management and remediation of soil
contamination. Metals, such as beryllium (Be), cadmium (Cd), nickel (Ni), and cobalt (Co) …

The electric polarizability and the spread of the total position tensors are used to
characterize the metallic vs insulator nature of large (finite) systems. Finite clusters are …

The localization spread gives a criterion to decide between metallic and insulating behavior
of a material. It is defined as the second moment cumulant of the many-body position …

We examine a class of Hamiltonians characterized by interatomic, interorbital even-odd
parity hybridization as a model for a family of topological insulators without the need for spin …

Contrary to its small size, beryllium has been known to participate in anomalous bonding,
which disregards periodic trends and can present numerous theoretical challenges. Due to …
