Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for

The least primitive roots mod p

open access: yesJournal of Mathematical Cryptology
Let p>1p\gt 1 be a large prime number, and let ε>0\varepsilon \gt 0 be a small number. The established unconditional upper bounds of the least primitive root u≠±1,v2u\ne \pm 1,{v}^{2} in the prime finite field Fp{{\mathbb{F}}}_{p} have exponential ...
