Crystallographic texture dependent bulk anisotropic elastic response of additively manufactured Ti6Al4V

Description: This article identifies a bulk texture effect on elastic anisotropy in laser powder bed fused Ti6Al4V by employing an effective bulk modulus elastography technique coupled with ultrasound shear wave velocity measurement at a frequency of 20 MHz inside the material.

Discovery of higher-order topological insulators using the spin Hall conductivity as a topology signature

Description: This article shows a connection between spin Hall effect and HOTIs using a combination of ab initio calculations and tight-binding modeling. The model demonstrates how a non-zero bulk midgap spin Hall conductivity (SHC) emerges within the HOTI phase. This work guides novel experimental and theoretical advances towards higher-order topological insulator realization and applications.

Towards Deep Integration of Electronics and Photonics

Description: This is a review of applications of polariton modes related to the design and fabrication of electro-optical circuits. The emphasis is made on surface plasmon-polaritons which have already demonstrated their value in many fields of technology. Other possible quasiparticles as well as their hybridization with plasmons are discussed.
