This phenomenon shows the existence of fermion densities that are perpetually and perfectly periodic in time, and is comparable to the anomalous conductivity improvement in the Kondo effect.

[9] He made early predictions of the phenomenon of the Above Threshold Ionization (ATI) and the highly energetic electron emissions in one-dimensional atom models.

[13] In recognition of his work on the theory of electron localization in atoms and molecules, he was honored with the Frederic Ives Medal in 2010,[14] the highest award granted by The Optical Society of America.

[15] Eberly has longstanding research connections with Poland, publishing several papers with Polish physicist Adam Kujawski in the 1960s and 1970s.

[16][17][18] He has maintained a frequent scientific collaboration with 2022 Wigner Medal recipient Iwo Białynicki-Birula and was elected as a foreign member of the Academy of Sciences of Poland.

[citation needed] Their collaboration led to the discovery that the superradiant phase transition, originally observed at the University of Rochester, necessitates the existence of an “extraterrestrial” ether with a real and negative dielectric constant in the quantum vacuum.
