Molecules consist of one or more atoms bound together by covalent (chemical) bonds. Atoms may be depicted by circle shapes, each of which has a nucleus at the center (containing protons and neutrons), surrounded by one or more concentric circles representing the ‘shells’ or ‘levels’ in ...
What determines whether or not two atoms will bond to form a molecule? What occurs when an atom loses an electron? What type of bond results from the transfer of one or more electrons between interacting atoms? What kind of chemical bond produces crystalline lattices?
Moreover, the fidelity of two-atom gates often still lags behind that of one-atom gates in both trapped ion and neutral atom systems. Consequently, the proposed ququart architecture promises potential performance enhancements over traditional qubit systems. This potential is contingent upon maintaining...
The simulation results demonstrate that despite the meta-atom being split into several SMAs, they can still function collectively as a whole, since the powerful electromagnetic field among SMAs enables effective energy transfer. Meanwhile, the lossless material in the gap can, to some extent, reduces...
2 (a). Obviously, the lifetime τ2 measured in the as-quenched alloys is a superposition of positrons trapped in vacancies surrounded by one or more In atoms and in vacancy clusters. With increasing annealing temperature vacancy clusters gradually dissolve, where the released vacancies probably ...

Thus far in this chapter, we have discussed the various types of bonds that form between atoms and/or ions. In all cases, these bonds involve the sharing or transfer of valence shell electrons between atoms. In this section, we will explore the typical method for depicting valence shell elec...
Higher work function materials generally have stronger adsorption energies, which can result in more stable adsorption of gas molecules on the material surface. Upon gas adsorption, charge transfer can occur between the gas molecules and the material surface, leading to changes in the electronic ...
We define Pd atoms without a secondary Pd atom in the second shell coordination (i.e., 3.0 and 3.4 Å in PdO standard)17 as i-Pd1; and Pd atoms interacted with one or more Pd atoms in the second shell coordination as n-Pd1. Based on HAADF-STEM images, we estimate that Pd ...
one or more first electromagnetic fields tuned to excite a first transition between the state ground |g> and the state |r>, wherein the excitation of the first transition creates an entangled system comprising an entanglement of the pair of interacting multi-level systems; one or more second ...
