Abstract
ABSTRACT A microshot from FRB 20220912A (Hewitt et al. 2023) satisfies the uncertainty relation ΔωΔt ≥ 1 by a factor of only ⪅3. A Crab pulsar nanoshot (Hankins & Eilek 2007) exceeds this bound by a similar factor. The number of orthogonal plasma modes contributing to the coherent radiation is also ≈ΔωΔt, placing constraints on their excitation and growth.
