Maximizing the hyperpolarizability of 1D potentials with multiple electrons
Christopher J. Burke, Joseph Lesnefsky, Rolfe G. Petschek +1
We optimize the first and second intrinsic hyperpolarizabilities for a 1D piecewise linear potential dressed with Dirac delta functions for non-interacting electrons. The optim…
Optimizing the second hyperpolarizability with minimally-parametrized potentials
Christopher J. Burke, Joseph Lesnefsky, Rolfe G. Petschek +1
The dimensionless zero-frequency intrinsic second hyperpolarizability γ_{int}=γ/4E_{10}^{-5}m^{-2}(e\hbar)^{4} was optimized for a single electron in a 1D well by adjusting the sha…
Disordered, Quasicrystalline and Crystalline Phases of Densely Packed Tetrahedra
Amir Haji-Akbari, Michael Engel, Aaron S. Keys +4
All hard, convex shapes are conjectured by Ulam to pack more densely than spheres, which have a maximum packing fraction of ϕ = π/\sqrt18 ~ 0.7405. For many shapes, simple lattice…
Maximizing the hyperpolarizability poorly determines the potential
T. J. Atherton, J. Lesnefsky, G. A. Wiggers +1
We have optimized the zero frequency first hyperpolarizability βof a one-dimensional piecewise linear potential well containing a single electron by adjusting the shape of that pot…
