Searching for Dark Photons with a room-temperature dielectric haloscope
Siyin Li, Paschos Ioannis, Zhengyin Yang +4
We present a search for dark-photon dark matter with a room-temperature dielectric multilayer haloscope. The dielectric stack enhances photon conversion near 2 eV, and a spatially…

Absorption of Gravitons and Photon Luminosities of Interstellar/Intergalactic Hydrogen Atoms
George Savvidy, Pavlos Savvidis
We compute the emission and absorption rates of gravitons by hydrogen atoms. The absorption rate of gravitons is proportional to the number of hydrogen atoms and to the graviton lu…

Ultra-small Mode Volume Polariton Condensation via Precision Ion Implantation
Y. C. Balas, X. Zhou, E. Cherotchenko +7
We present a novel method for generating potential landscapes in GaAs microcavities through focused implantation. The ion beam imprints micron-scale patterns of non-radiat…
