Atomic scale visualization of topological spin textures in the chiral magnet MnGe

Autor: Repicky, Jacob, Wu, Po-Kuan, Liu, Tao, Corbett, Joseph, Zhu, Tiancong, Ahmed, Adam, Takeuchi, N., Guerrero-Sanchez, J., Randeria, Mohit, Kawakami, Roland, Gupta, Jay A.

Spin polarized scanning tunneling microscopy is used to directly image topological magnetic textures in thin films of MnGe, and to correlate the magnetism with structure probed at the atomic-scale. Our images indicate helical stripe domains, each cha

Surface structures of the magnetostrictive D03-Fe3Ga(001)

Autor: Ruvalcaba, Ricardo, Corbett, J. P., Mandru, Andrada-Oana, Takeuchi, N., Smith, Arthur R., Guerrero-Sanchez, J.

First-principles total energy calculations and experimental measurements were performed to study the surface reconstructions of the magnetostrictive Fe3Ga alloy. The magnetostrictive behavior was evaluated in the bulk by compressing and stretching it

A Circuit-Level Amoeba-Inspired SAT Solver

Autor: Takeuchi, N., Aono, M., Hara-Azumi, Y., Ayala, C. L.

AmbSAT (or AmoebaSAT) is a biologically-inspired stochastic local search (SLS) solver to explore solutions to the Boolean satisfiability problem (SAT). AmbSAT updates multiple variables in parallel at every iteration step, and thus AmbSAT can find so
