Irreducible axion background

K Langhoff, NJ Outmezguine, NL Rodd - Physical Review Letters, 2022‏ - APS
Searches for dark matter decaying into photons constrain its lifetime to be many orders of

A generic formation mechanism of ultralight dark matter solar halos

D Budker, J Eby, M Gorghetto, M Jiang… - Journal of Cosmology …, 2023‏ - iopscience.iop.org
As-yet undiscovered light bosons may constitute all or part of the dark matter (DM) of our
Universe, and are expected to have (weak) self-interactions. We show that the quartic self …

Submicrometer perovskite plasmonic lasers at room temperature

S Cho, Y Yang, M Soljačić, SH Yun - Science Advances, 2021‏ - science.org
Plasmonic lasers attracted interest for their ability to generate coherent light in mode volume
