Subatomic disruptor

From Memory Alpha, the free Star Trek reference.

A subatomic disruptor is a 29th century weapon which disrupts matter at a subatomic level.

The Federation timeship Aeon was equipped with a subatomic disruptor. (VOY: "Future's End")

The subatomic disruptor seems to be superior to the 24th century shields and weapons, as a small ship with one "fighter-sized" weapon was a challenge for a much larger vessel like the USS Voyager. As the technology was unknown to the crew, the subatomic disruptor must have been invented between the 25th and 29th century. It is also unclear how much this future weapon has in common with the more familiar disruptor.
