Joseph Henry Eberly (born October 19, 1935), is an American physicist. He is a Professor of Physics, Astronomy and Optics at the University of Rochester. [1] [2]
Joseph Henry Eberly was born in 1935. He completed a Bachelor of Science degree in Physics at Pennsylvania State University in 1957 and obtained a Doctor of Philosophy in Physics at Stanford University in 1962. His doctoral advisor during his PhD program was Edwin Thompson Jaynes, which helped him connect with Eugene Wigner. [3]
Eberly's research interests include Cavity quantum electrodynamics (QED), quantum information, control of non-classical entanglement, the response of atoms to high-intensity optical pulses, and coherent control theory of optical interactions. [4] In 1995, he founded the Rochester Theory Center for Optical Science and Engineering (RTC) with funding from the National Science Foundation. [4]
Eberly contributed to understanding the quantum revival in the Jaynes-Cummings model. [5] In a 1966 paper on electron self-energy, he revealed aspects of the Higgs mechanism in electrodynamics, demonstrating how massless particles can acquire mass through interaction with the Higgs field. [6] Additionally, Eberly has studied atomic vapor laser isotope separation. [7] [8]
In 2003, he discovered the phenomenon of crystallization in time for highly excited states of atoms. 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. He also observed a similar phenomenon in the emission of highly energetic deuterium nuclei from the ultra-cold strong laser driven deuterium droplet clusters. [ edition needed ] These clusters are considered alike to giant atom with deuterons acting as heavy electrons, and the electrons acting as their gluons or nucleus. Eberly also observed the cold-hot nuclear fusion in such systems. [10]
Eberly has received the Charles Hard Townes Award, [11] the Smoluchowski Medal and the Senior Humboldt Award. [12] In 2007, he served as the president of The Optical Society of America. [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. In 2012, the Society recognized his many years of service with the Distinguished Service Award. [13] In 2021, he was appointed as an honorary member of Optica (formerly 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. [19] Eberly has also co-authored multiple publications with Kazimierz Rzazewski, who served as both his M.Sc. and Ph.D. supervisor. [ 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. [ citation needed ] This finding challenged the notion that classical electromagnetic gauge fields alone could cause such a phase transition, aligning with the electromagnetic version of the Bohr-van Leeuwen theorem. [20]
Eberly has published over 350 scientific journal articles, as well as other scientific papers. He has also authored three graduate textbooks. [21]
Spontaneous emission is the process in which a quantum mechanical system transits from an excited energy state to a lower energy state and emits a quantized amount of energy in the form of a photon. Spontaneous emission is ultimately responsible for most of the light we see all around us; it is so ubiquitous that there are many names given to what is essentially the same process. If atoms are excited by some means other than heating, the spontaneous emission is called luminescence. For example, fireflies are luminescent. And there are different forms of luminescence depending on how excited atoms are produced. If the excitation is effected by the absorption of radiation the spontaneous emission is called fluorescence. Sometimes molecules have a metastable level and continue to fluoresce long after the exciting radiation is turned off; this is called phosphorescence. Figurines that glow in the dark are phosphorescent. Lasers start via spontaneous emission, then during continuous operation work by stimulated emission.
Atomic, molecular, and optical physics (AMO) is the study of matter–matter and light–matter interactions, at the scale of one or a few atoms and energy scales around several electron volts. The three areas are closely interrelated. AMO theory includes classical, semi-classical and quantum treatments. Typically, the theory and applications of emission, absorption, scattering of electromagnetic radiation (light) from excited atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter in general, fall into these categories.
Coherence expresses the potential for two waves to interfere. Two monochromatic beams from a single source always interfere. Wave sources are not strictly monochromatic: they may be partly coherent. Beams from different sources are mutually incoherent.
Anton Zeilinger is an Austrian quantum physicist and Nobel laureate in physics of 2022. Zeilinger is professor of physics emeritus at the University of Vienna and senior scientist at the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences. Most of his research concerns the fundamental aspects and applications of quantum entanglement.
Anthony E. Siegman was an electrical engineer and educator at Stanford University who investigated and taught about masers and lasers. Known to almost all as Tony Siegman, he was president of the Optical Society of America [now Optica (society)] in 1999 and was awarded the R. W. Wood Prize in 1980, the Frederic Ives Medal in 1987, and the Esther Hoffman Beller Medal in 2009.
Paul Bruce Corkum is a Canadian physicist specializing in attosecond physics and laser science. He holds a joint University of Ottawa–NRC chair in attosecond photonics. He also holds academic positions at Texas A&M University and the University of New Mexico. Corkum is both a theorist and an experimentalist.
In physics, a trojan wave packet is a wave packet that is nonstationary and nonspreading. It is part of an artificially created system that consists of a nucleus and one or more electron wave packets, and that is highly excited under a continuous electromagnetic field. Its discovery as one of significant contributions to the quantum mechanics was awarded the 2022 Wigner Medal for Iwo Bialynicki-Birula

Double ionization is a process of formation of doubly charged ions when laser radiation is exerted on neutral atoms or molecules. Double ionization is usually less probable than single-electron ionization. Two types of double ionization are distinguished: sequential and non-sequential.

In quantum optics, a superradiant phase transition is a phase transition that occurs in a collection of fluorescent emitters, between a state containing few electromagnetic excitations and a superradiant state with many electromagnetic excitations trapped inside the emitters. The superradiant state is made thermodynamically favorable by having strong, coherent interactions between the emitters.
