Massively parallel pixel-by-pixel nanophotonic optimization using a Green's function formalism
Jiahui Wang, Alfred K. C. Cheung, Aleksandra Spyra +3
We introduce an efficient parallelization scheme to implement pixel-by-pixel nanophotonic optimization using a Green's function based formalism. The crucial insight in our proposal…
Inverse design of photonic devices with strict foundry fabrication constraints
Martin F. Schubert, Alfred K. C. Cheung, Ian A. D. Williamson +2
We introduce a new method for inverse design of nanophotonic devices which guarantees that resulting designs satisfy strict length scale constraints - including minimum width and s…
Hund's coupling stabilized superconductivity in the presence of spin-orbit interactions
Alfred K. C. Cheung, D. F. Agterberg
The intraorbital repulsive Hubbard interaction cannot lead to attractive superconducting pairing states, except through the Kohn-Luttinger mechanism. This situation may change when…
Residual spin susceptibility in the spin-triplet, orbital-singlet model
Yue Yu, Alfred K. C. Cheung, S. Raghu +1
Nuclear magnetic resonance (NMR) and Knight shift measurements are critical tools in the identification of spin-triplet superconductors. We discuss the effects of spin orbit coupli…
Superconducting tunneling spectroscopy of spin-orbit coupling and orbital depairing in Nb:SrTiO
Adrian G. Swartz, Alfred K. C. Cheung, Hyeok Yoon +4
We have examined the intrinsic spin-orbit coupling (SOC) and orbital depairing in thin films of Nb-doped SrTiO by superconducting tunneling spectroscopy. The orbital depairing…
Weiss oscillations and particle-hole symmetry at the half-filled Landau level
Alfred K. C. Cheung, S. Raghu, Michael Mulligan
Particle-hole symmetry in the lowest Landau level of the two-dimensional electron gas requires the electrical Hall conductivity to equal at half-filling. We study the…
