Time-variant parity-time symmetry in frequency-scanning systems
Frequency-scanning systems with narrow instantaneous linewidth hold promise for various fields. Here, the authors report the use of time-variant parity-time symmetry to dynamically narrow the instantaneous linewidth of frequency-scanning systems.
Optical skyrmions from metafibers with subwavelength features
Current optical skyrmion generators involve complex bulky systems, hindering further practical applications. We propose an integrated metafiber for high-quality photonic skyrmions, with subwavelength polarization features and topology tunability.

Earthquakes under a volcano near Alaska’s largest city raise concerns
ANCHORAGE, Alaska (AP) — An increase in the number of earthquakes under a volcano near Alaska’s largest city this year has geologists paying attention.
Mount Spurr, about 80 miles (129 kilometers) northwest of Anchorage, last erupted in 1992, spewing an ash cloud nearly 12 miles (19 kilometers) into the air, prompting flights to be canceled and people to don masks. Another eruption at the 11,100-foot (3,383-meter) stratovolcano could be severely disruptive to the city, according to the Alaska Volcano Observatory.
The observatory raised its alert status for Mount Spurr in October — from green to yellow — when the increase in seismic activity became pronounced and a ground deformation was spotted in satellite data. Observatory scientist David Fee said Friday there have been about 1,500 small earthquake below the volcano this year, compared to about 100 in a normal year.
