For example, if we have a particle with velocity v, charge z (in a unit of elementary charges), traveling a medium with electron number density n and mean excitation energy I, we can calculate the mean energy-loss using the formula: $$\begin{aligned} -\left\langle \frac{d E}{d x...
Finally, (6.2) can be rewritten(6.5)1+βx0q=β+x0dβ,after some simple algebra using formulae for H, H′ and x0≡z01/β. Compare , above with (2.18) and (2.19) in Karatzas and Wang (2000, pp. 263, 264), respectively. 6.2. Pricing an “up-and-out” barrier put-option of...
The results of the prism refractometer were compared to the weather station method, where the air temperature, pressure and humidity were measured and the refractive index calculated using the modified Edlin equation17,18. In Table 1, the velocity of light compensation (V.O.L.) was calculated ...
The behavior of a two-dimensional light bullet propagating with a velocity greater than the speed of light in a medium consisting of semiconducting carbon nanotubes is investigated by means of numerical simulation. The electromagnetic field of the investigated system is described using Maxwell's equatio...

Nevertheless, most of the results are also valid for new conductive 2D materials, e.g., high-quality graphene, in the frequency range where conductivity can be described with the Drude formula [36,37]. We describe plasmons in the simplest classical manner using Maxwell’s equations and the ...
Quantum droplets are ultradilute liquid states that emerge from the competitive interplay of two Hamiltonian terms, the mean-field energy and beyond-mean-field correction, in a weakly interacting binary Bose gas. We relate the formation of droplets in sy
3.By means of uniting geometry with algebra, the arc length, tangent line, cotangent space and curvature of curve in four dimensional space are investigated, and the corresponding calculation formula in each cases are given.用形数结合的观点研究了四维空间中曲线的弧长、切线、法空间和曲率问题,并给出...
