The code used for the radiation patterns is publicly available via the pyGDM2 library50. The one-dimensional time-dependent finite-difference code is available from J.H. (jakob.huepfl@tuwien.ac.at) on reasonable request. References Poynting, J. H. XV. On the transfer of energy in the ele...
What is an example of a force in physics? The most common examples of forces are gravitational and normal forces. Gravitational force is a non-contact force and is an attractive force between two objects with mass. For example, Earth exerts a gravitational force on the Moon. Normal force is...
The Boltzmann equation, also known as the Boltzmann transport equation describes the statistical distribution of particles in a fluid. It is an equation for the time evolution of f(r,c,t), the particle distribution function in the phase space. Phase space can be viewed as a space in which ...
aIn physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything—a single generative equation for all we see 在物理,一种方法采取这种冲动为统一对它的极端,并且寻找一切的理论唯一生产等式为我们看见的所有 [translate] ...
Indeed, since we are trying to drive the state u to rest at time t = T, the oscillations of the density coefficients ε could be a major obstacle for doing that. Note however that, as mentioned in the introduction of this section, there is no example of heat equation with bounded ...

Our analysis is valid for any periodic function of time m(t), but here we will focus on the classic sinusoidal case m(t)=M[1−cos(ΩMt)], (6) with M the modulation depth, ΩM≡2π/TM, and TM the modulation period. In the case of FM modelocking, M should be ...
The nonlinear SchrÖdinger equation is the most typical equation for the development of slowly changing quasi-monochrome wave packets in weak nonlinear media with dispersion, whereas the linear SchrÖdinger equation represents the time evolution of the wave function59. It simulates a number of ...
