What is the meaning of divergence in physics? Give an example. Explain tidal waves, what make them, why they are so in different phases of the moon. Explain qualitatively the phenomenon of interference of waves. What are the conditions for maxima and minima?
A transport theory for atomic matter waves in low-dimensional waveguides is outlined. The thermal fluctuation spectrum of magnetic near fields leaking out of metallic microstructures is estimated. The corresponding scattering rate for paramagnetic atoms turns out to be quite large in micrometer-sized wa...
A double-edged sword in two-dimensional material science and technology is optically forbidden dark exciton. On the one hand, it is fascinating for condensed matter physics, quantum information processing, and optoelectronics due to its long lifetime. On the other hand, it is notorious for being ...
Such an extended definition of wavenumber is commonly used in wave physics44 to describe evanescent waves. By doing this, Eqs. (2) and (3)-(5) have the same form as for 1D wave scattering (see Supplementary Note 1 for the comparison). The two components of the field F(x) appear to...
The basis of proposed analysis is to consider mixing on a photodetector of two coherent vector waves with variable states of their vectors of polarization. Vectorial optical signal for spectral analysis is considered in framework of Fraunhofer diffraction for scattering of two plane vector waves by ...
Since the conjugated parameters cannot be measured simultaneously, it is the integral of the Wigner function along one dimension that has a meaning of a probability distribution in the conjugated dimension. For instance, the integral of the Wigner function along the time dimension provides the ...
The cutoff around 𝑛=𝑘𝑎n=ka means that such contributions do not propagate, exactly as happens for the evanescent waves produced by planar sources. Analogous behavior has been observed in the past for spherical and cylindrical scalar sources [23,24,45]. 5. The Basis Functions as ...

A slight variation on the meaning comes in the sense of something that is united clearly as a whole and a recognizable entity. You might say, for example, that New York City is a "culturally coherent region" within the United States....
