A Spectral Method for the Eigenvalue Problem for Elliptic Equations Let [OMEGA] be an open, simply connected, and bounded region in [R.sup.d] d [greater than or equal to] 2, and assume its boundary [delta][OMEGA] is smooth... K Atkinson,O Hansen - 《Electronic Transactions on Numeric...
Bound states in the continuum (BICs) are ubiquitous in many areas of physics, attracting special interest for their ability to confine waves with infinite lifetimes. Metasurfaces provide a suitable platform to realize them in photonics; such BICs are rem
Graphene’s nonlinear conductivity is calculated using semiconductor Bloch equations based on graphene’s tight-binding model by Cheng et al.14,15. These values can be transformed to the nonlinear refractive index using30 $${n}_{2}=\frac{3}{4{\varepsilon }_{0}c({{n}_{graphene}}^{2...
Under the travelling wave transformation, some nonlinear partial differential equations such as Camassa-Holm equation, High-order KdV equation, etc, are reduced to an integrable ODE expressed by u'' + p(u)(u')2 + q(u) = 0 whose general solution can be given. Furthermore, combining complet...
Nonconstant solutions of the Yang–Mills equations can be considered in the form of series of perturbation theory using all constant solutions as a zeroth approximation.doi:10.1142/S0217732323500967Shirokov DmitryWorld Scientific Publishing CompanyModern Physics Letters, A...
Finally, as the SH intensity is proportional to the absolute square value of the second-order polarization, we retrieve equations (2) and (3) shown in the main text: $$\begin{array}{lll}{I}_{\mathrm{AC}}^{2\omega }&=&| {P}_{\mathrm{AC}}^{(2)}{| }^{2} \propto | {E}...
