Due to the axial symmetry of the electrostatic potential in the GQD, we can describe the eigenstates by the orbital quantum number m (here, we neglect spin). In the absence of the GQD, the eigen-energies \({E}_{Nm}\) have infinite orbital degeneracy [\({\psi }_{Nm}({{{\bf{r...
Atomic-level qubits in silicon are attractive candidates for large-scale quantum computing; however, their quantum properties and controllability are sensitive to details such as the number of donor atoms comprising a qubit and their precise location. This work combines machine learning techniques with ...
When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. How do I read the periodic table? Th...
The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
(110) crystal plane of TiO2, respectively (Fig.2g–i). In addition, the presence of irregular lattice stripes indicates a large number of structural defects in the MXene/TiO2hybrids. Meanwhile, the introduction of TiO2nanoclusters promotes the formation of interfaces, including interfaces between ...
Related efforts are those of JAC [21] and Pairinteraction [22] programs. However, a growing number of research groups are now working on Rydberg states of atoms with two valence electrons [23], such as the alkaline earth elements (e.g., Ca, Sr) and some of the lanthanides (e.g., ...
(PCA) was applied to reduce the dimension of each subimage, where nine principal components represented 98% of the variability in the features. At this point, we can see the power of using the Patterson function method to reduce segmentation errors and greatly reduce the number of significant ...
whereEPdCu,EPd, andECudenoted the energy of the PdCu alloys, the energy of one Pd atom in the bulk, and the energy of one Cu atom in the bulk, respectively. Here, m and n represented the number of Pd (or Cu) atoms in the alloy, respectively. The slab was treated with both of ...
However, the conditions that need to be satisfied by the rows and columns of a unitary matrix, as well as the requirement that the determinant of the matrix should be +1, reduce the number to eight independent real parameters. These eight parameters lead to eight generators of the SU(3) ...
A clear trend between the ALD cycle number and peak separation can be seen in Fig. 5a, highlighting the ability to accurately control the number of layers, down to 2 layers, or less, with 8 ALD cycles63 with a peak difference of 22.5 ± 0.1 cm−1. The films had a clear...
