In this paper, the energy and momentum operator substitution method derived from the Schrödinger equation is used to list all possible light and matter wave equations, among which the first light wave equation and relativistic approximation equation are proposed for the first time. We expect that...
7. Furthermore, the energy density equation and the equation of heat conduction were compared. 在此基础上,考虑边界的反射作用,推导了有限大板的能量密度控制方程,得到了能量密度的近似解,并通过位移解得出了能量密度和声强的解析解。 8. The model has been generalized to the condition with dissipation, wh...
A) Speed of light 1. **方程背景**:E=mc²是爱因斯坦提出的质能等价方程,描述质量与能量的关系。 2. **符号解析**: - E代表能量(Energy),对应选项B是干扰项。 - m代表质量(Mass),对应选项C与问题无关。 - c是真空中的光速(Speed of light),为恒定值约3×10⁸米/秒,题目中选项A正确。
The resulting models couples a system of diffusion equations for the electron (or light particle) density and energy (the so-called energy-transport model), with a hydrodynamic system of Euler type for the ions (or the heavy species). We have pointed out that the conventional models which ...

The uniform deformation energy density model is also based on the assumption that Young’s modulus is anisotropic. Eq. 15 can be used to get the energy density or energy per unit (u) for an elastic system that obeys Hooke's law. (15)u=ε2Yhkl2 Therefore, the W-H model can be rewri...
light-matter quantum coherence is relevant. Here we set a rigorous and general ME framework, the coherent ME (CME), that overcomes both limitations. The CME predicts strong deviations from Haus ME, which we substantiate through an amplitude-modulated semiconductor laser experiment. Accounting for ...
We give a physical motivation for this choice using laser light pressure. As a consequence of our derivation, the energy momentum stress tensor for the total source matter and fields must be divergence free, when spacetime is 4 dimensional. Moreoverr, if the total source matter fields are ...
A second-order differential equation is derived for the electric potential of an electron system with slowly varying density. It includes consistently the first-gradient corrections to both the kinetic energy and the exchange energy. In the regime of high density, the equation reduces to the one ...
