Spin-resolved band topology and its relationship to spin-electromagnetic response effects can most straightforwardly be understood in 2D insulators. To begin, we consider a 2D spinful (fermionic), noninteracting insulator lying in the xy-plane with s = sz spin-rotation symmetry (i.e., U...
Figure 1 provides an overview of the three aspects of integrated quantum communication: photonic materials platforms for large-scale integration36,37,38, quantum photonic components such as quantum light sources39, high-speed modulators40 and highly efficient photodetectors41, and typical applications in...
1. Mathematics A geometric figure formed by a point moving along a fixed direction and the reverse direction. 2. a. A thin continuous mark, as that made by a pen, pencil, or brush applied to a surface. b. A similar mark cut or scratched into a surface. c. A crease in the skin...
Figure 2. Time series of weekly water level at Belesar reservoir: (a) complete time series (since 1964); and (b) time series since 2009, when data from upstream measuring stations are available. Table 1. Descriptive statistics for the dependent variable (water level at Belesar reservoir) ...
Figure 1. Experimental system of the “TIG + AC” twin-wire cross arc additive manufacturing. Experiments show that the transfer mode of the twin-wire droplet can be controlled by changing the speed of twin-wire feeding (V1 on the left, V2 on the right). In the deposition, the droplet...
The data was obtained for a series of liquid superficial velocities (0.053-0.66 m/s) and gas velocities between 3 and15 m/s. The figure illustrates that the void fraction depends on both gas and liquid flow rates but that the dependency is not strong. This is not unexpected from published...
Two straight wires of infinite length, located in the x0y plane, extend parallel to the x axis and at a distance a from it(the distance between the wires is2a). The wires have linear density charge\lambda and−\lambda.
figure salaries, but it’s no small amount if you combine our wages. The Parks are investing a great part of their fortune in our family. So let us give thanks to Mr. Park, our generous employer. A great man. And how can I forget Min-Hyuk! How lucky that our son is friends wit...
Ordinarily, the wire would seem electrically neutral, with no net positive or negative charge, because the wire has about the same number of protons (positive charges) and electrons (negative charges). But if you put another wire with a direct current next to it, the wires attract or ...
