Maximal violation of Kirchhoff's law in planar heterostructures
نویسندگان
چکیده
The ultimate energy-harvesting efficiency (93%) is made possible by violating Kirchhoff's law of radiation. Using a planar nonreciprocal structure, complete violation can be achieved. In addition, this planer structure does not require any coupling beyond the light cone.

Planar Voronoi cells: the violation of Aboav’s law explained
In planar cellular systems mn denotes the average sidedness of a cell neighboring an n-sided cell. Aboav’s empirical law states that nmn is linear in n. A downward curvature is nevertheless observed in the numerical nmn data of the Random Voronoi Froth. The exact large-n expansion ofmn obtained in the present work, viz. mn = 4+3(π/n) 1 2+ . . ., explains this curvature. Its inverse square root ...
متن کاملMaximal Neutrino Mixing and Maximal CP Violation
We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T viola...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

We consider supersymmetric grand unified theories with soft supersymmetry-breaking scalar masses [Formula: see text] specified above the GUT scale (super-GUTs) and patterns of Yukawa couplings motivated by upper limits on flavour-changing interactions beyond the Standard Model. If the scalar masses are smaller than the gaugino masses [Formula: see text], as is expected in no-scale models, the d...
متن کاملMaximal Flavor Violation in Super-GUTs
We consider supersymmetric grand unified theories with soft supersymmetry-breaking scalar masses m0 specified above the GUT scale (super-GUTs) and patterns of Yukawa couplings motivated by upper limits on flavour-changing interactions beyond the Standard Model. If the scalar masses are smaller than the gaugino masses m1/2, as is expected in no-scale models, the dominant effects of renormalizati...
