Research interests are quantum-mechanical perturbation theory, summation of divergent perturbation series, quasiclassical methods for resonant states. Specifically, Stark effect and 1/D-expansion (where D is the dimensionality of space) for various quantum-mechanical problems, such as screened Coulomb potentials, Stark and Zeeman effects, helium-like ions, and two-centre-Coulomb problem. Recently, worked on self-consistent-field version of the semiclassical perturbation theory for molecules, new schemes to sum perturbation series for resonances, estimating stability of atoms with a variable nuclear charge (finding "critical" charges). asergeev.com

Stark spectroscopy

Stark spectroscopy or electroabsorption spectroscopy is a form of UV/Vis spectroscopy, where the sample is exposed to a strong electrical field. This induces small changes in the energy of the electronic levels of the material under investigation and thus small differences in the absorption spectrum.

The technique is named after Johannes Stark.

Johannes Stark (April 15, 1874 - June 21, 1957)

was a prominent 20th century physicist, and a Physics Nobel Prize laureate.

Born in Schickenhof, Bavaria, Stark was educated at the Bayreuth Gymnasium (grammar school) and later in Regensburg. His collegiate education began at the University of Munich, where he studied physics, mathematics, chemistry, and crystallography. His tenure at that college began in 1894; he graduated in 1897, with his doctoral dissertation regarding some physics subjects of Isaac Newton.

He worked in various positions at the Physics Institute of his alma mater until 1900, when he became an unsalaried lecturer at the University of Göttingen. He worked and researched at physics departments of several universities, including the University of Greifswald, until 1922. In 1919, however, he won the Nobel Prize in Physics for his "discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields" (the latter is known as the Stark effect). From 1933 until his retirement in 1939, Stark was elected President of the Physico-Technical Institute, while also President of the Deutsche Forschungsgemeinschaft.

Stark published more than 300 papers, mainly regarding electricity and other such topics. He received various awards including the Nobel Prize, the Baumgartner Prize of the Vienna Academy of Sciences (1910), the Vahlbruch Prize of the Göttingen Academy of Sciences (1914), and the Matteucci Medal of the Rome Academy. He married Luise Uepler, and they had five children.

During the Nazi regime he attempted to become the Fuhrer of German physics through the Deutsche Physik ("Aryan physics") movement (along with Philipp Lenard) against the "Jewish physics" of Albert Einstein and Werner Heisenberg. From Wikipedia, the free encyclopedia.

Aryan Physics?
When the Nazis entered the political scene, Lenard quickly attempted to ally himself with them, joining the party long before it was fashionable to do so. With another Nobel Prize in Physics laureate, Johannes Stark, Lenard began a core campaign to label Einstein's Relativity as Jewish Physics, decrying it was overly abstract, out of touch with reality, associating it with moral relativism, and, the icing on the cake, practiced exclusively by Jews and Jewish sympathisers.
For a few years in the early 1930s, this found strong support from Nazi leadership, as it played upon a number of Nazi ideological themes, and gave yet another method to harass Jewish citizens and institutions. Lenard and Stark enjoyed the Nazi support because it allowed them to undertake a professional coup for their preferred scientific theory; an example of using heavy-handed politics to influence the results of a "paradigm shift." Under the rallying cry that physics should be more "German" and "Aryan," Lenard and Stark, with backing from the Nazi leadership, entered on a plan to pressure and replace physicist positions at German universities with people teaching their preferred theories (by this time, the early 1930s, there were no longer any Jewish physicist professorships in Germany, since under the Nuremberg Laws Jews were not allowed to work in universities). Stark in particular was also trying to get himself installed as the Führer of physics—not an entireably fanciful goal, given the Gleichschaltung (literally, "coordination") principle applied to other professional disciplines, such as medicine, under the Nazi regime, whereby a strict linear hierarchy was created along ideological lines. - From Wikipedia, the free encyclopedia
