Arnold Johannes Wilhelm Sommerfeld, ForMemRS (German: [ˈzɔmɐˌfɛlt]; 5 December 1868 – 26 April 1951) was a German theoretical physicist who pioneered developments in atomic and quantum physics, and also educated and mentored many students for the new era of theoretical physics.
Apr 22, 2024 · magnetic quantum number. orbital. Arnold Sommerfeld (born Dec. 5, 1868, Königsberg, Prussia [now Kaliningrad, Russia]—died April 26, 1951, Munich) was a German physicist whose atomic model permitted the explanation of fine-structure spectral lines.
Nov 16, 2023 · Sommerfeld's most notable contribution to theoretical physics is evident in his development and expansion of quantum theory. Working on the foundations laid down by Niels Bohr, Sommerfeld introduced elliptical and asymmetric orbits into the atomic model, significantly improving the accuracy of spectral predictions.

Dec 6, 2015 · Arnold Johannes Wilhelm Sommerfeld was a German theoretical physicist and renowned mentor of fellow physicists (he has supervised the greatest number of Nobel prize winners of any other supervisor). His notable achievements include the introduction of the 2nd and 4th quantum number, as well as x-ray wave theory. Sommerfeld.
Sommerfeld’s work in mathematics led to important contributions in partial differential equations in physics and the theory of gyroscopes. He then turned to the study of atomic spectra. In 1915, he suggested that the circular orbits of the Bohr atom should instead be elliptical ones and postulated a new, azimuthal quantum number to specify ...
Sep 1, 2010 · He is also known for writing some of the first atomic- and quantum-physics textbooks. Atombau und Spektrallinien (Atomic Structure and Spectral Lines), Sommerfeld’s problem-oriented treatise on the old quantum theory, first published in 1919, was revised almost annually until 1924.
Nov 20, 2014 · Michael Eckert has written a remarkable biography of Arnold Sommerfeld (1868–1951), the “off-scale” theoretical physicist who made his Seminar at the University of Munich the outstanding school of theoretical physics of the first third of the twentieth century.
