David Snoke

from Wikipedia, the free encyclopedia

David W. Snoke (* 1961 in New Jersey ) is an American solid-state physicist .

Life

Snoke graduated from Cornell University and received his PhD from the University of Illinois at Urbana-Champaign in 1990 . He worked at the Aerospace Corporation and as a post-doctoral student at the Max Planck Institute for Solid State Research with Manuel Cardona . He is a professor at the University of Pittsburgh , where he has taught since 1994.

In 2006 he became a Fellow of the American Physical Society . In 2016 he received the APS Outstanding Referee Award.

Snoke and his group investigate fundamental physical problems with methods of semiconductor physics such as the conductor-insulator transition and quantum phase transitions , formation and loss of coherence in Bose-Einstein condensates (BEC), non-equilibrium phenomena with the Boltzmann equation in quantum mechanics and the validity of the second law in of quantum field theory . He is known for his pioneering work on Bose-Einstein condensates of polaritons in micro-cavities (traps), which he and his group achieved in 2007.

He researches electronic transport with polaritone BEC (light-induced superconductors ) and materials that bring the polaritone condensate phenomena into the range of room temperature.

Intelligent design, science and religion

In 2004 he wrote an essay with the biochemist Michael J. Behe , which was heavily criticized because it was used by Behe ​​as a support for intelligent design ( irreducible complexity ). In 2014, Snoke published another paper on the formation of structures with new functions in evolution. According to the authors, on the way to new functional structures in evolution, many specimens with not yet functioning, i.e. useless structures, have to be observed, which is not the case. They therefore concluded that it would be fine-tuned . Snoke also argues that modern systems biology is in fact making the case for intelligent design. In 2006 he published a book A Biblical Case for an Old Earth (Baker Books) on the occasion of a debate among Presbyterians (Snoke is one of them) whether the earth is billions of years old (old earth) as science teaches or only ten or twenty thousand at most Years (young earth). Snoke believes that the old earth position is compatible with the Bible and even with its orthodox conservative interpretation (not just a liberal interpretation).
