TL;DR: The low-threshold, continuous-wave operation of a subdiffraction nanolaser based on surface plasmon amplification by stimulated emission of radiation is reported on, opening a scalable platform for low-loss, active nanoplasmonics.

TL;DR: This report reports on the first demonstration of broadband tunable, single-mode plasmonic nanolasers (spasers) emitting in the full visible spectrum and successfully reduces the continuous-wave (CW) lasing thresholds to ultrasmall values for all three primary colors and clearly demonstrated the possibility of "thresholdless" lasing for the blue plas monolaser.

TL;DR: In this paper, a SPASER-enabled nanolaser comprised of a subdiffraction plasmonic cavity and a single InGaN@GaN core-shell nanorod gain medium was used for low-threshold, continuous-wave (CW) operation.

TL;DR: Using atomically smooth epitaxial silver films, new optical permittivity highlighting significant loss reduction in the visible frequency range was extracted in this paper, confirming the low intrinsic loss in silver.

TL;DR: It is demonstrated experimentally that canted antiferromagnetic BaMnSb2 is a 3D Weyl semimetal with a 2D electronic structure, indicating the system is Weyl type due to time-reversal symmetry breaking.
